How hard is it to replace a fuel filter?

Hey there
I am a total newb when it comes to car repair. I can do the usual stuff, oil change, I recently fixed my parking brake (pretty proud of myself on that one) but I'm pretty inexperienced. So with all that said, is changing the fuel filter something I SHOULD be able to do? I am terrified of wrecking my baby. BTW I have a 1998 Wrangler TJ Sport. 4 cyl 2.5 l. Opinions would be much appreciated.

NOW ----------- You have just TOTALLY CONFUSED the entire Issue !!!!!!!!
When trying to share some GOOD advise about Your Brake / Turn light issue, I THOUGHT (PER YOUR GARAGE PROFILE) that we were looking at a 2013.

PROPER INFORMATION listed in Profiles GOES a very long ways when seeking out HELP.
Just thought I'd mention that little tid bit there Mate.

Ha! Sorry brother, unintentional confusion there. And to make matters MORE confusing, I just read somewhere else on the internet that TJs don't have fuel filters?! Can that be right?

Check this video at about minute 4:23. He says that "the Jeep TJ doesn't have a fuel filter". Really?

First the good news... your TJ's OE fuel filter has a positively huge (!) surface area and very likely does not need to be changed. Ever. The factory designed it that way so it is officially a "lifetime" filter. It looks like a big round piece of dense white felt.

The only time I'd worry about changing it would be if the Jeep was running on third-world gas that wasn't well filtered like U.S. gas is. The days of needing to change or clean the old-style inline fuel filters are pretty much over for most vehicles.

The bad news is that if you insisted on changing it, you'd have to drop the gas tank to get to it. The fuel filter is sealed inside the fuel pressure regulator which would have to be replaced in order to replace the fuel filter inside.

This is the fuel pressure regulator I'm holding in my hand, the TJ's fuel filter takes up most of the room inside. You can see the old fuel pressure regulator I'm replacing still in place on top of the gas tank below. I was replacing the FPR because its check valve was leaking & letting the gas drain back out of the engine making for slow starts.

Thanks Jerry! This is amazingly helpful. And thanks for the pics, I'm a little slow and it makes thing really obvious. Looks like if I'm having any stalling it could be something else. Thanks!

Yep stalling is not likely to be from a clogged fuel filter.

If is stalling try cleaning the IAC.

I know this is a total noob question but what's the IAC? Thanks for the help.

IAC is the Idle Air Control which is mounted on the throttle body. Its job is to provide all of the engine's air at idle RPMs when you're not stepping on the gas to open the throttle body valve plate.

Go buy yourself done throttle body cleaner. Remove air intake tube. Leave car running and put it in where the intake tube was pour slow until your engine stalls out. Do this at least twice. Then out back together.

Warning: when you start up you will blow a bunch of crap out of your exhaust and you will throw a cel (check engine light)

there is only a fuel strainer on the bottom of the sending unit. It is a mesh bag. costs around 15.00.
You need to drop the tank, <make sure its near empty>and remove the sending unit.
I threaded ring, and it pulls out. The strainer bag is right at the bottom.

What do you mean there is only a fuel strainer?

I know what it all looks like, it is just confusing when you say there is only a fuel strainer at the bottom. Your wording simply makes it sound like you are saying there is no fuel filter, only a fuel strainer.
