Replaced Fuel Filter

According to WJJeeps.com

"All WJ models have two fuel filters, a strainer filter at the bottom of the fuel pump module inside the fuel tank and one exterior filter within the fuel pressure regulator. Both filters are designed for extended service. They do not require normal scheduled maintenance. Filters should only be replaced if a diagnostic procedure indicates to do so".


Not sure how long that extended service is, but after 12 years and not knowing if the fuel filter was service by the previous owner, I decided to change it due to poor idle and starting.

Bought a new fuel filter from Advanced Auto, cost about $27.00 bucks. I was looking for the WIX brand but no one in my area was selling it, not even NAPA.


Next was to find the fuel pump fuse from the diagram and pull it from the housing. its number 29.

Just match it with the diagram and pull it.

After fuse is pulled, start the engine until it stalls, do it a couple of times then open up gas tank to release pressure.
Disconnect negative terminal from battery.
Jack up vehicle and crawl under to find fuel filter, it is located near the left coil spring. ( not sure about V8 location if the same )

The connection for the line on the right can be released by squeezing the blue plastic retainer. ( note: the hose is a little bit tough to pull off, so use a little elbow grease )
Same process for the UPPER hose on the other side.

The connection with the rusted part is a bit tricky, took me awhile to figure out how to remove it without using any special tools ( fuel line remover ).
I was using my door panel remover to push back the black quick-connect back to the hose to release it so I could pull the whole thing off. ( see illustration http://www.wjjeeps.com/misc/quick_connect.pdf )If I wasnt laying on the ground doing it maybe it would have been easier.
( I read that some were using a regular open wrench to push the quick-connect back ) Sorry could not take pictures how I had it set up, Need an extra hand for that....

Once all hose connections are removed, use a 10MM socket to remove the screws to pull the fuel filter. Dont worry if the retainer comes with it, you can remove it carefully and put it back in the housing.

Quick comparison

Reverse the process all the way to reattaching the battery cable and check for leaks once you've restarted the engine.
The filter installed!

My idle was smoother after replacing the old filter and engine starting was also quicker..... I dont think Im going to wait another 12 years to replace this. I might do it every 12000 miles.

The GUNK.


the fuel dripping from this filter was dark brown.....

Re: Replaced Fuel Filter

Nice writeup. I changed my filter/regulator a while back as well, due to acceleration problems i had. Also thought it a bit strange that this filter/regulator is not an item that should be changed periodically. When you took the filter appart, did you see the actual pressure regulator as well? (just curious)
The removal of the hoses gets a bit easier when you put some lubricating spray in the connections. It can wash out accumulated road dirt and let the connection slide of easier.
The item numbered 29 is not the fuse, but the fuel pump relay, but the effect is the same.

Re: Replaced Fuel Filter

Yes, you are correct. It is the pump relay! Thanks for pointing that out.

There was a round metal piece inside that I saw but did not bother to take pictures of it, I threw the whole thing right after takng he picture. Sorry man...

Re: Replaced Fuel Filter

There is probably not too much to see and for sure nothing to do with the pressure regulator, i was just wondering where it was hidden away.
But i do appreciate a picture though.

Re: Replaced Fuel Filter

Great write up! I have a filter sitting here, I tried to do it a while ago when I did my O2 sensors, but I was unable to get that one line off. The 2 push in connectors were easy, but that black disconnect gave me trouble, and I didn't want to break it. Looks like I will have to get the tool and try it again. I can only imagine what mine looks like!

Re: Replaced Fuel Filter

Just did mine. 2 push in clips went well. Removed them from the old filter and put them on the new. The black quick disconnected needed some love. Used a 10mm open ended wrench to push it in. Squeezed the wrench with fingers and thumb on the bracket, that did the trick sans special tool.

After dinner will get it off the jacks and quick run and check for leaks.

Thanks for the write up.

Re: Replaced Fuel Filter

Yeah, that black disco was a pain, thinking of getting the $10 dollar tool kit to make it easier next time. Just not sure if once every 12K use is worthit, but then again its a cheap investment and wont really hurt the pocket.....

Sounds good, I will have to try that next time! I'm kinda sick of laying under this thing right now...
