I have an airtex fuel pump in my 89 cherokee and it's insanely loud, and also it's made for a 20 gallon tank, which I don't have. I've been to every parts store looking for one that will fit and I can't find one that will actually fit in her besides the airtex one. any suggestions on what to do? I bought one today that is "supposed" to be the oe pump but when I brought that home it wouldn't fit in my old assembley. I'm at a loss on what to do, I didn't think finding a fuel pump would be this hard. I know threads like this are on here constantly but I would love anyone's advice on this situation.

 

89 and 90 fuel pumps are the same? if so, found one like i need at autozone.com
they priced it fer 101.99 in store and ship to home.

 

Yeah I think their the same, it's probably the airtex pump. Im just hesitant about having that in there because all these forums say their bad and don't work, and I am having a problem every once in a while where the jeep either wont keep an idle or when I'm accelerating sometimes it will feel like it stops getting gas, and then gets gas again or something. I figured maybe that had something to do with it being a 20 gallon pump and my jeep only having a 13 gallon tank. That and sometimes it gets so loud that I can't even hear my stereo. I'm not 100% sure that's a fuel issue but I just assumed it had something to do with that pump. Im very confused on the entire situation haha.

 

Sounds just like mine. Fires right up to 3000rpm, then fizzles out and dies. Replaced the ballist and filter, still nothing. Gonna let the jeep sit the rest of the mnth till the first, then replace the pump.

 

I have had nothing but problems with Airtex fuel pumps. Because of that and because countless others have had the same results with their stuff, I won't install them, nor will I recommend them to anyone.

 

Has anyone found any other pumps that work? I just tried a delphi brand pump from oriley's but that wouldn't fit in the original assembly. The jeep's been doing a lot better now since I've replaced the tps, Im just still a little weary about that pump considering it's for a 20 gallon tank, would that cause any problems or anything?

thanks for all the help!

 

just wondering what size tank you have. and personally i dont think it'd cause a prob, as long as the gas reaches the pump.

 

I have the Bosch in mine and it is working good.

 

if you haven't bought one yet, i recommend www.rockauto.com i bought my fuel pump from there a few months back. was cheaper than an autozone or other parts stores. no problems with it yet. ive bought a few other things from them, so far all good experiences. mine was a pain to put back in, there's a little hole you have to get the pump into for it to fit correctly.

 

Have you put a code reader on? Even if theres no CEL, there might be something stored in there that will give you a direction. You said it runs better since the TPS was replaced, what about the rest of the ignition stuff- plugs, wires, cap, rotor, good, clean battery leads and wires. And last but not least, o2 sensors... What condition are they in?

 

Hey man im having alot of the same issues although i have a twenty gallon tank... my pump went out i replaced it and the new one worked but hummed like a mother (and everyone knows they hum loud!)and it also was doing the runn good, then act like it wasnt getting fuel song and dance, BTW it was an Airtek, so i warrantied it, put another new Airtek in, Still hums. i have noticed the fuel is pretty dirty coming out so me and a buddy were thinking maybe its dirty fuel plugging lines?!?!?! idk man but honestly it just sounds like stay away from airtek and go from there so after christmas thats my next step. i also called a dealer here in PHX that says they could replace it and warranty it for 300 so if i get too pissed i will just take it there and take it in the short i guess rather than setting fire to my beloved jeep!!! So have you fixed this problem since?!?!?!? if so how? thanks from one person with the same problems to another!

 

Had to change the fuel pump in my 89, went through three pumps still couldn't find the right one. Got on the napa site and found a pump pn p74302 fit perfect, about 130 buck but it was well wort it. Hope this will help.

 

ok but yours just wasnt fitting properly tho right? did yours ever hum real loud? thats what mine is doing as well as some other ppl but i have an airtek pump so maybe i just need to try a bosch or carter, damn those cheap airteks should be banned!!!

 

I had issues with airtex also

 

It was a while ago (06), but I just installed whatever Napa handed me in my 90. It's been fine. I'm sure it would work in a 13 or a 20 or a milk jug! My O'Rileys loans things like fuel pressure testers free with a deposit equal to it's new cost, and you don't need to return it!
