What is the fuel filter and how does it work?

The fuel filter is made of cellulose or synthetic-based filter media that traps extremely tiny contaminants, such as rust particles and dirt, present in the fuel as it flows from the fuel tank to the fuel injectors. The filter media is sealed within a cylindrical shaped housing that looks like a tiny soda can. You will most often find the fuel filter plumbed into the high-pressure fuel supply line beneath the car, right next to a sturdy frame rail. Some fuel filters, particularly on diesel-powered vehicles, have water traps as well. Some newer cars do not have serviceable fuel filters as the filter is built into the fuel pump located in the fuel tank.

When to consider replacing the fuel filter:

  • Scheduled maintenance. The most common reason to change the fuel filter — your vehicle’s maintenance schedule may specify a filter change interval.
  • Fuel contamination. If any foreign fluids, bad fuel, or water enters into the fuel system mistakenly, the fuel filter should be replaced.
  • Fuel system repairs. If the fuel pump has been replaced, work has been performed on or in the gas tank, or the fuel injectors have been cleaned or replaced, always install a new fuel filter. Major engine repairs, or engine replacement, also require a new filter.
  • Leaks. There should be zero leakage of fuel, whether liquid or vapor, in the fuel system. Leaks at the fuel filter connections might necessitate not only a new fuel filter but also new O-rings in the push-on connections to the fuel filter.
  • Warning light indication. Diesel powered vehicles may be equipped with a water-sensor warning light circuit to signal the driver if excessive water has accumulated in the fuel filter. The water will have to be drained and the filter possibly serviced or replaced.

How do mechanics replace the fuel filter?

  • A clogged fuel filter that is integral to the fuel pump must be removed with the fuel pump from the fuel tank to perform service.
  • For all other vehicles, the procedure begins with raising the vehicle and supporting it with steel jack stands.
  • The fuel system is depressurized so the filter can be removed from the high-pressure fuel line without gas spraying out.
  • The in-and-out connectors to the filter are removed and the filter is removed from the fuel line.
  • The new filter is installed using a small amount of oil on the O-rings to ease re-installation of the quick connect fittings. The fuel system is then checked for leaks while the engine is running.

Is it safe to drive with a fuel filter problem?

Yes, so long as the fuel filter is not leaking. If there is a leak, have it repaired before driving the car. If clogging is suspected and potentially causing engine operating problems, have the cause investigated and resolved at your earliest convenience. In extreme cases, a very old filter that may be plugged could disintegrate, allowing what were trapped contaminants to reach the fuel injectors and causing additional problems.

When replacing the fuel filter keep in mind:

  • A plugged fuel filter can be ruled out using pressure and volume tests on the fuel system. Given enough elapsed mileage though, all fuel filter replacements should be done as basic maintenance, and so complicated tests are not necessary if the filter is already known to be old.
  • Consult the vehicle maintenance schedule to determine when to replace the fuel filter.
  • If you have bought contaminated gas, once all fuel system repairs are made, always install a new filter.
  • Gasoline is perishable and will eventually degrade into compounds that will damage the fuel system. Generally, if a car has sat unused with gas in the tank for more than 3 to 6 months, the gas should be drained and the fuel filter replaced.

98 1995 - Oil Pressure Light is on - Houston, TX
They just sent an email saying the mechanic is on his way. It is only 8:12 am! He is off to a good start. He is supposed to arrive between 9:00-9:30 am. He arrived well before that time! It was not 9:00 am yet! He did a diagnostic and he checked all the work I did. He said I did great work with everything I did. He said the car is very good shape. He said this car is indeed a runner! He checked everything. He checked all the fuses and relays too. He did a complete diagnostic too. He checked fuel pressure, oil pressure, and more. He found out what it was. It had nothing to do with oil pressure or anything. The fuel pump is going out. When he came the car started right up. He said they never go totally out. He said that is why it started when it did. He connected tools I do not have to the Ninety Eight. It is not getting any fuel pressure, and this is why it shut off all the times it did. He fixed one of the spark plug wires too. It was burnt. He jacked the Ninety Eight up and got underneath and checked the wires, the oil pressure sensor/switch and oil level sender for everything and the connections and made sure they have power and were installed correctly. He said the engine uses oil pressure along with the fuel pressure to start. The fuel pressure is non existent and that is why it would not start. After all of that, he looked at the Oldsmobile Toronado, my other car . He got the air conditioner to work again. He said the compressor bolt was loose and he tightened it up. He used this huge screw driver device and bent it back in place. He said the shims were loose and he bent them back. It cools just fine now. We turned it on and off several times testing it. He checked the pressure and it was filled with refrigerant. He checked the relays and the fan too. It was all fine. He said it is clear you take care of both of your cars. He said one thing I will not do is guess and I like to know what is indeed wrong. He said your cars are in good shape. He said you do not need valve cover gaskets. There is no leak. I booked him to return to install the fuel pump I need. I look forward to seeing him again soon in a few weeks. Today only cost me 70.00. That's it.

98 1995 - Oil Pressure Light is on - Houston, TX
The mobile mechanic came. I must say I am impressed! He found my house. He and I started talking. He said he owned two Ninety Eights previously. He was there to look at my Oldsmobile Ninety Eight. He had two Oldsmobile Ninety Eight Touring Sedans. The ones he owned were from the 1987-1990 era. He was describing the floor shifters and they had and how much he liked Ninety Eights, Touring Sedans, and the Oldsmobile Eighty Eight LSS too. He talked about how a family member owned one and how he was fixing his. He talked in detail about the Touring Sedan and the things he loved. He asked me how long had I owned my Ninety Eight. I told him 2003. He told me how he become a mechanic and went to school for it and more. He got into the Ninety Eight and it would not start. He got out and disconnected the battery and rubbed the negative and positive battery terminals together. He reconnected them and the Ninety Eight started! The instrumentation then told him exactly what it was. There is a sensor at the bottom of the oil pan. He said by doing what he did with the terminals, it cleared the computer and reset it. We went underneath the car and he showed me the sensor. He said which one did you replace? I told him. He said you were on the right path. You know what you are doing. You need to replace this sensor and not the one you did. You can get the sensor and replace it because it is clear you know what you are doing and on the right path. He said you also need to replace your valve cover gaskets. They are leaking. I told him I will request him to come back and do that. I am not doing that even thought I can.
