Then take module out and put new one in and reinstall. DO NOT forget that the fuel filter on 97 zj and up fuel filter is in the tank. Get the new "sock" when you get the pump some stores dont sell it with but as an accessory.


If you replace a pump and it goes bad and the company finds out you did not replace the sock it will void the warranty. you wouldnt believe how many people would yell at me at advance auto becasue airtex wouldnt replace the pump after they didnt replace the sock and i told everyone this and nobody believed me. i would say roughly 50 people who brought the pump back after it went bad after a week or two it was because they sucked everything through the dirty sock..... the new pump has a stronger pull then the old worn out one so it sucks all the dirt and crap from the dirty sock and dirt in the tank and pre maturaly wears out the pump and it goes bad, that is why they void the warranty if you dont replace it (that is what i was told from an Airtex rep)

well some autopart stores give you the option on buying the sock. They will not tell you about the warranty, and for the fact about Airtex fuel pumps if you run them on 1/4 tank or less to many times they will go bad! Unlike Mopar or Ac Delco parts. Now from personal knowledge on doing fuel pumps NO matter how much fuel is in the tank drain it all out and clean the tank PERIOD and get 5 gallons of new gas and put it in the tank and then let the customer goto the gas station!

Airtex must love trouble , if they were not such a cheap company , they would include a new sock on every pump . Bosch did

Just the fact that Airtex would use an electrical wire grommet in the top of some of their fuel pump assemblies which is not fuel resistant and can cause a fire is enough for me to want to stay away from their products. While this recall for some Jeeps w/Airtex fuel pumps is 7-8 years old there's still a lot of bad reviews and problems with their current fuel pump products. No thanks.

You replaced the whole assembly right? Check the main connector you had to disconnect to drop the tank. You indexed the float to the same posistion?

I replaced the whole unit. And as far as the float goes, as soon as I set it in the tank, it adjusted to the level of the gas.
I read to that to check the fuel pump relay? The article said that this also controls the gauge as well. Is this true?

No it runs. My gauge is on empty. Fuel lite on. And DTE on overhead counsel is 0. I figured it was the pump, so I replaced it. Still goose eggs.

ooooo gotcha. do you have access to a schematic? im not exactly sure where the fuel pump gets power from or where it goes. if you know for a fact that the pump is a good pump and all then all you can do is start spanning out from the pump and figuring out where the reading goes. i would personally drop the tank and get a multimeter and ensure that the pump is sending a signal out. you have to start somewhere and find the issue thats where i would start. ill look around and pass on any info i can, good luck dude

Thanks. I also read somewhere that the fuel pump relay sends out a reading to as well to the gauge too. I hope that works. Prob get a relay switch tomorrow.

well all, i just wanna say thanks for the help. i found my problem and now the gauge is working and the lite is off. ending up being a wiring issue. i wish i would have looked first since now im out 150 for a new pump. but, i know now that the pump is new. the wiring was was at the grommet underneath the vehicle right before u go into the jeep. one wire was disconnected with the other 3 severed.
so i butt-connected all 4 wires, wrapped them up nicely with electrical tape, and put the loom back over. good to go now!!
thanks once again all!!!
