This results in fuel starvation, especially during times when the engine is too demanding. Only a fuel filter replacement would offer a lasting solution. You can use a fuel line disconnecting tool to make this easier. A clogged filter restricts the flow of fuel. A disadvantage of these types of filters is their inaccessibility, which makes them difficult to service. Let us get started. That is the reason we came up with this fuel filter guide. A fuel filter is a simple device that is installed in a fuel system to screen out contaminants. Required fields are marked *. Not useful on its own as it does not explain how efficiently a filter does that. With the many fuel filter types available, it can be daunting to choose the kind that suits your vehicle. Most modern automobiles use in-tank fuel filters. When that amount is unavailable, the process cannot begin. Eventually, it would reach a point where the engine fails to start or stalls in the middle of a journey. With the fuel lines out of the way, you can now remove the fuel filter. They included paper element, cloth element, felt element and also the combination of cloth and felt element. A less conventional but still useful method entails observing the flow of fuel when the engine is running. If the fuel filter has lasted for or more than two years, it could be about time you replaced it. However, they are not a final word, and you may need to examine the filter itself. Base Plate- the part at the end of the filter housing where device mates with the mounting assembly. Diesel contains some amounts of wax, which may crystallize in low temperatures. The process only involves unfastening the damaged filter and fastening a new one in its place. Absolute micron rating is more useful than nominal rating when describing a fuel filter. This results in an inconsistent supply of fuel to the engine, and the reason for the hard starting. If there is not sufficient flow of fuel, it means the filter is clogged. Read chapter by chapter, and learn more about this crucial part of an automotive fuel system. Use a screwdriver to do that. Otherwise, you may experience compatibility issues where the new filter does not fit its mounting place. When used for a fuel filter, micron rating indicates the filter’s ability to capture contaminants of a specific size. In this section of the fuel filter guide, we will look at the fuel filter parts in a typical gasoline and diesel fuel filter. Many modern vehicles also have the fuel filter built into a “fuel pump module,” which eliminates the need for scheduled replacements. This is because they often precede the secondary filters in the fuel system and do not need to capture the finer impurities. View Details. This is due to the extremely tight clearances of the injector nozzles. Fuel Filter Service Scheduled fuel filter replacements are often ignored in the quick lube bays because they are more difficult and time-consuming to perform. This small device helps your car’s engine to perform at its optimum as well as last a long time. It will cause a restriction in the fuel flow. You may also want a fuel filter that can withstand high pressures if the engine uses diesel fuel. Others mount in the fuel tank separate or as part of the fuel pump. Schematic of a fuel filter/separator. If you are fond of driving on an empty tank, the fuel filter cannot last its lifetime. The fuel will not burn efficiently, resulting in less power. It allows the fuel from the tank and straight to the engine unfiltered. Hence to get rid of this unwanted dirt, filters are used. A micron rating of 10 microns means the filter removes particles that are 10 microns and above, while a 5 micron rating shows a filter capable of trapping impurities of size 5 microns or larger. Some fuel filter types feature a plastic housing that is see-through. Oil filters are usually a spin-on design, while fuel filters mount using several means. Owning a vehicle for more than two years and using it constantly means you will have a fuel filter to replace. Diesel, on the other hand, naturally contains more impurities, specifically water and excess wax. With the introduction of direct-injected engines, there was the need for a filter that could withstand the high pressure levels in the fuel system. Place a container underneath the fuel filter to catch any fuel that may come out of the fuel lines or filter. What are the symptoms of a bad fuel filter? It is one of the most common fuel filters in today’s automobiles. Check to see that the filter is identical to the old one both in the inlet/outlet diameters, size, and other design features. For spin-on filters, the threads should match. It is, therefore, advisable to ensure that the other parts of the starting system are working correctly. Diesel serves as a lubricant for the engine parts. To make diesel more usable, manufacturers often install a primary filter to remove particles, water, and wax and a secondary filter to catch the remaining pollutants. When installed before a fuel pump, a fuel filter also serves to protect the pump from abrasive particles. Start and run the engine for a few minutes. A partially clogged filter would cause a slight restriction to the flow of fuel. Gasoline systems usually depend on a single filter. Center Tube- the center tube supports the filtration and prevents it from collapsing inwards. Examine the new filter to ensure it is the right one for your vehicle. Fuel filters come in different sizes, shapes, and so on. In summary, a fuel filter in an automobile prevents the following. In terms of position, these filters mount on the pressure side of the fuel pump, which is usually nearer to the engine. Because checking engine light can be turned on by a range of issues, it is recommended to have the computer scanned for problem codes. To do this: These filters offer better engine protection but cost ore than cellulose filters. The filters feature an inlet on the fuel pump side and an outlet on the other. The centri… As a result, there may be no noticeable loss of engine power. The housing can be plastic or metal depending on several factors. Cellulose media can be treated to give it water filtration capabilities. Next, remove the two plastic clips that secure the fuel filter. Also many other Internal Combustion Engine Parts. This causes the fuel pump to work harder. Here is a fuel filter micron rating chart showing values for Beta Ratio and efficiency levels. Usually derived from tests, which can be a single pass test or multi-pass test. In such cases, changing the filter may not help much. There are two types of Fuel fi lter: Fuel/Water Separators (FS) – Separate water from the fuel and remove large contaminants Fuel Filters (FF) – Remove the smaller contaminant particles from the fuel The Cummins Filtration fuel product line also includes: Fuel Strainers (in-tank and inline) to capture very large particles It is good to note that a clogged filter is not the only cause of starting issues in a vehicle. Nominal Micron Rating indicates the percentage of specific particle size that a filter can remove. A damaged or clogged fuel filter starves the engine of fuel. Several other components can lead to the problem. The increased pressure is then enough to overcome the restriction of the filter media. It is the first component that cleans fuel of large contaminants such … They can be natural or synthetic. The diesel engine life is mostly depended on the quality of fuel and lubrication of internal parts.

To withstand the differential pressures created in the filter, manufacturers make this part from sturdy material, usually steel. Its function is to filter out most of the contaminants- the large particles and particularly water and wax. Locating the fuel filter is easy. On the other hand, diesel fuel filters are larger and mostly two in a fuel system. Also, a filter that stresses the fuel pump over time to cause damage. When the pump has to force fuel through this kind of filter every driving time, it is likely that it will break down too soon. Some fuel filter types, specifically those in diesel engines, contain a mechanism to remove water from the fuel. Each has its upsides and downsides. Fuel filters come in different designs, shapes, sizes, and internal constructions. Regardless of whether you change the filter yourself or take the vehicle to a mechanic, it is necessary to have the right filter installed. To help you decide on the fuel filter to buy, we compiled a list of the factors to consider. Fuel filters exist in different types and designs. With fewer metal or plastic parts to throw away, changing this type of filter is less impacting on the surroundings. This happens when the filtration media is too clogged to allow fuel through. Changing the fuel filter would fix the problem. Fuel filters can last for between 30 000 to 50 000 miles. The next chapter delves into the fuel filter parts, with a description for each. However, look for a filter that is not too cheap. A clogged fuel filter causes a reduction of fuel pressure in the system. Re-insert the fuse. Heating oil filters: choose, install, service & repair guide, oil filter types, sizes, capacities used on oil fired boilers, furnaces, water heaters How to change the oil filter cartridge and how to bleed air out of oil filter canisters Reasons to install double parallel heating oil filters on oil fired equipment - two oil filters? There are three main fuel filter types: the pretank filter, primary and secondary filters. This is the problem that is picked by the sensors to indicate a problem with the engine. If a manual transmission vehicle, that means ensuring the car is in neutral and with the parking brake engaged. They do not usually feature a mechanism to extract water from fuel, which means a less complicated construction. This means the filter curves down. Although no too apparent, bad fuel filter warnings can help you restore engine performance. For others, it means replacing the whole device. After all the other considerations, it is essential to choose fuel filter brands carefully. Particulate matter in fuel causes wear in the different engine parts due to their abrasive nature. Where these are removed out frequently, through drain plug fitted at the bottom of the bowl. A typical micronic fuel filter with changeable cellulose filter element. Disclosure: Some Affiliate Links and Third Party Advertisement Links are used by this Site. These are the car make, model, year of manufacture, and type of fuel system. They only have a few parts that make them up. If it contains water, the lubricity reduces, and the engine may overheat. Where it drops large dust particles at the element, and then this fuel flows out centrally. By screening out contaminants, a fuel filter acts as an engine protector. Water collects in the bottom of the bowl, while an open/close valve at the bottom of the bowl allows the water to drain from the basin, leaving only water. As a result, fuel filters exist in various shapes, sizes, and other construction differences. If the fuel pump is damaged, there is a reason to suspect a clogged filter to be the cause. Oil filters are also a bigger size when compared to most fuel filters. If an already clogged filter is left on a vehicle, it reaches a point where the flow of fuel is substantially reduced. These impurities need to be removed, or the engine’s performance and health will be affected. The available fuel is then enough to start the engine but inadequate to keep the vehicle going. By  capturing contaminants, the filter helps to ensure optimal engine performance. When suction created by the fuel feed pump, the fuel from a fuel tank is sucked through the filter element. When their lifespan is over, the whole device needs to be removed and thrown away. That means choosing carefully to ensure only the best fuel filter for your type of vehicle, fuel system, and other aspects. A fuel filter’s location, therefore, depends on several factors. The early filters were are small plastic can. Cellulose is less restrictive and will pass adequate amounts of fuel even when the filter is clogged to a certain level. To locate the fuse box, use your car’s manual, or look up the manufacturer’s website. So, it will cause an appreciable drop in engine performance. When buying a fuel filter for your vehicle, it is essential to take into account every consideration. Precaution: gasoline is highly flammable. A by pass system is used to attain higher pressure drop across the filter and also to make the filtration process slower and efficient. The Fuel filter is used to remove the impurities present in the fuel to avoid the disturbance during the flow. Fuel filters trap foreign material that may be present in the fuel and prevent it from entering the carburetor or sensitive fuel injection components.. With fuel passing through the filter under low pressure, there was no need for an elaborate or high-strength device.

That often happens when particles clog most of the pores of the filtration media, leading to a restricted flow of fuel. Your email address will not be published. Secure the vehicle by ensuring it is not in gear. For those that use automatic transmission, it should be in park. A centrifugal filter can also be used in a by-pass system. A clogged fuel filter is not the only problem that would cause starting difficulties. Some vehicles come with a dashboard indicator light that is triggered by changes in fuel pressure, lean fuel, engine misfire, and several other issues. As is the case with other vehicle parts, a fair price is what you should go for. You will need to replace the old one with a similar type, or you will encounter installation problems. stainless steel, etc. These filters mostly remove particles that are larger than 10 microns. During such situations, you may find that you can still crank up the engine. This filtered fuel enters the next stage (Fine Filter Element). The filtration media can be different types, each with own advantages and disadvantages. Insert the new filter in the bracket and replace the fuel lines. That also means the lifespan of a microglass fuel filter will be shorter than that of cellulose media. Fuel filters use different materials for the filtration media. When the water from fuel has reached a critical level, the sensor sends a signal that lights up a dashboard signal. Diesel filters are bigger and mostly bowl-shaped Depending on the fuel system used, a vehicle may use a primary filter or both primary and secondary fuel filters. A type of synthetic filter media, microglass offers better filtration for the finer impurities. It will drop the impurities and enter into the centre perforated tube. That is around two to three years. Secondary filters do not remove water from fuel, only the smaller particles that are less than 10 microns. Cellulose fuel filters are mostly used in gasoline and diesel fuel systems. These include a dead battery, a bad starter motor, starter relay or solenoid, and a few others. Contaminants can get into the fuel in many ways. Diesel engines also have fuel filters that look and function differently from those used by vehicles that run on gasoline. Mostly, it occurs when going uphill or accelerating, and the demand for fuel is high. Others will have a window to allow you a view of the internal components. The perforated centre tube is surrounded annularly by a filter element. Because they screen the fuel that goes to the engine, fuel filters are mounted anywhere between the fuel pump and the engine. A filter in good working condition ensures air going into the engine does not contain abrasive particles. Depending on the size of the pores, fuel flows through, while particles remain behind. This filter also provides a high quality air-fuel mixture which is essential for proper and complete combustion of the fuel. End Cap- the supporting structure that holds the filter media in place. Faulty fuel filter symptoms may indicate a problem such as clogging or filter element damage. It may also deliver contaminated fuel. Usually, the make, type, and year of manufacture of your vehicle can guide you towards deciding a matching fuel filter. A less restrictive filter will, on the other hand, cope with a high flow rate fuel system.
