  • There is no real way of knowing when to change a fuel filter. I recommend changing it every 50,000 miles. A clogged fuel filter will overwork your fuel pump, which can require costly repairs, maybe not tomorrow or next week but it will eventually cause the fuel pump to fail. For as cheap as a fuel filter is usually 15 dollars it will save you hundreds.

Fuel filter is located inside the fuel tank so you have to remove you fuel tank to replace the fuel filter. I had a problem with mine and had to replace the fuel pump and filter at the same time.

Where is the fuel filter on a 2005 Kia Spectra EX?

2005 Kia Spectra does not contain a external fuel filter but rather has a fuel filter in the fuel pump it self. The filter in the pump is said to be a lifetime filter, but can be replaced if desired. The only time to replace the filter is if the pump itself is being replaced or serviced, otherwise its not necessary to replace

Trouble shooting fuel pump on 2000 blazer how do I know its the fuel pump for sure?

Have someone turn the ignition to the on position without starting the engine. At the same time you should listen at the fuel filler door with the cap off. If you hear the pump run you know the fuse and relay are good. If you hear nothing check the fuse and replace the relay. If you hear it run then the fuel pump is running but is not pumping fuel or your fuel filter is clogged. Replace the fuel filter before proceeding any farther. If after replacing the filter you are still not getting fuel the pump is defective.

How do you change fuel filter on 2001 Pontiac Gran Prix?

The fuel filter is in the gas tank. It has been industry practice for a long time. You might as well replace the fuel pump and fuel sending unit while you're in there.


How do you replace fuel filter in a 2004 vibe?

You have to have the gas tank dropped. The fuel filter is actually a sock placed over the intake inside the gas tank. It's in your best interest to go ahead and replace the fuel sensor that's located inside the tank too. Total project to have a mechanic do for me was about $300. (the biggest part of the bill being labor). If it's time to replace the filter, it's definitely worth it to have them replace the sensor at that time to save you down time and money.

In 2004 Chevy moved the fuel filter from the drivers side frame rail and put it inside of the fuel tank.
