Do I have a real fuel filter?

My dad and I want to replace the fuel filter and maybe fuel pump in my 98 ZJ 5.2l Laredo. I read on one of the threads that i might have a pump and strainers in the tank and then a fuel filter on top of the tank. I looked at advance auto, autozone, and oreilly auto and none of them have any fuel filters for sale for my jeep.....so whats up? do I have a fuel filter or not?

Not sure about the filter, but I know NAPA sells the strainers.

If yours is like mine (I have no reason to believe not...) you have an external fuel filter on the drivers side of the fuel tank, forward a little bit. You should be able to see it clear as day if you crawl under there and take a look.

I replaced mine about a year ago. It was not exactly tricky. Just be sure to have a gallon jug or something to catch any fuel in the lines before you plug them.

Good Luck!

Oh, also, replacing the pump is also a good idea if your gas gage doesn't read correctly. The resistor tend to loose their functionality after awhile.

I just got off the phone with the parts dept. at the dealership and he said there isnt a fuel filter on a 5.2l laredo. I have to replace the fuel pump, and that is the fuel filter. Anyone know where there is a writeup for a fuel pump change on a 5.2 zj?

Dang, you are right. research @ rockauto.com shows that they stopped putting fuel filters in the 5.2L in '97. Funny, I thought they stopped in '99 when they changed the models....
Oh well. Good luck!

If it's the same as my 94ZJ it's easy(other than everything that has to come first.)
Remove your hitch/skid first.
Put a jack under your tank with a board to make it easier to handle the tank. Disconnect the filler lines.
unbolt the tank straps and slowly lower the tank. undo the wires/hoses from the fuel pump. take the locking ring off.
Then reverse order to instal.

Don't forget to disconnect the battery as well OP.

On the 97 through 99 models use the in-tank fuel filter, wonder what engineer at Jeep came up with that great idea. The 2000 and up use am external fuel filter but it is part of the fuel pressure regulator.

Correct!
No external fuel filter on the '98.

You mean 97-98 have in-tank filters. WJ's had a regulator/filter combo piece which isn't hard to change, but it is pricey as hell. Again, thanks to genius engineers.

I can see it now:

"Hey bob, check out where I put the fuel filters on the new jeep"
"LOL that's mean, you have to change it back"
"I can't, it's already in production"
"......."
