How To Replace Fuel Filter


Rob_M

Recommended Posts

Can replacing the fuel filter be performed by a noob or not? I'm not afraid to try it but I just want to know if it is easy to do. If so how do you do it? I do have a manual I can look in but in a nut shell, does it just pop out and pop back in or what?

Thanks, ROB :huh:

There's probably a tool needed to remove the fuel lines from the filter, and there is a way for you to remove fuel pressure before you remove the lines. Not quite sure how you do that for your year and model, i just did mine a couple days ago, after purchasing the tool, it took 15 minutes to do. If its rusty, spray some lubricant on the connections to loosen it up a bit.

Good luck!!

I believe that you can pull the fuel pump relay and start the engine till it dies.. to relieve the pressure...I usually do it first thing in the morning when there is no real pressure built up...

By the way, I showed you an expensive tool in that email, you can buy a cheapo fuel line disconnect tool in any autoparts store... Mike

I don't believe you need a fuel line disconnect tool for the fuel filter. After relieving the fuel pressure, blow off any dirt from the connections with compressed air and then depress the two tabs on the fitting, rotate the fitting 1/4 turn each way and pull apart.

When reassembling use some engine oil on the fuel filter nipples to lube the o-ring and help installation. Verify that the connection is tight and then check for leaks.

It all depends on the gas you get. It can last a lifetime if your fuel comes from a new station with new fiberglass tanks. It can get clogged with one fill up if the fuel comes from an old rotted steel tank full of sediment and you fill as a tanker is unloading, stiring up all the sediment in the bottom.

Thanks Ranger. Looks like I have been lucky so far, but I'll consider replacement some time in April.

Alright, it's finally done. I finally broke out the jack and took a look at it. Then it wasnt so hard after I was half way there. Its just one bolt to drop it down, then I removed the old filter. I read somewhere that you could also pull the fuse for the fuel pump and let the gas run out, I skipped that step though. The hardest part was disconnecting the clips because I didn't wan't to kink the fuel lines. Once I figured it out, I just started snapping it back together. I made sure both sides "clicked" on the filter to the hoses, and that the arrow was pointing in the direction of the fuel, then drove it and checked for leaks.Hey thanks again everyone. Saved $42 bucks! :D
