Default Airtex fuel pumps

These piles of crap are sold at the automotive chain stores. I'm using one in my supercharged Jeep 4.0. The first one was bad out of the box. The dead headed pressure was only 40 psi.
They have me another with no hassle. This pump has worked for about a month and is now doing the same thing. Hard starting when the pump warms up and no longer makes decent pressure.

Save your time and money and buy a real walbro.

Airtex is made by Walbro, FWIW. The pumps that failed to meet OEM specs are retested with less strict standards and if passed sent to aftermarket, at least thats how it was about 7 years ago when I worked there.

It is an in-tank pump. The pump still works, it just cannot supply what it is supposed to. Priming the pump used to get 45 psi with the first turn of the key. Now priming the pump nets about 5 psi. A couple more key primes might get 15 psi.
When the pump is cold it primes properly. 45 psi first time. After the pump runs for a while it gets weak. 12 volts is still being fed to the pump. No voltage degradation.

A new bbk/walbro 190 did the trick.

idk what application you bought the airtex pump for but i know of very few vehicles that operate at pressures higher then 45 psi. a stock 4.0 operates around 40 psi. i would guess the reason the pump failed was because you were asking more from it then it was designed for. i have used airtex pumps in stock applications with a very low failure rate. less then 2% i would guess.

I agree 100% with buttercr125, they are garbage, longest i have seen one last was a year, I hate doing a job more than once due to junk parts. Never again will i install one even if the customer brings me the part.

I'm using it on my supercharged 4.0. At wot pressure was dropping from 45 to 30's. It would also crank for 5 seconds before starting.
As soon as I make boost the new walbro hits 90 psi. Now I have to recalibrate or most likely remove the fmu.

These pumps are junk. Considering all the work it takes to replace one it only makes sense to not buy walbro's quality control rejects.

Like I said after all the issues that I have had I will never install them again. Since then I have had customers bring me an Airtex pump and ask me to install them. I explained to them that they where of poor quality and I would not install them anymore. Even after explaining why I won't they still don't understand and want it installed anyway.

I have also had vehicle brought in on a wrecker that the customer tried to fix by installing a Airtex pump and it still wouldn't run. When I told him it was probably the pump he told me there was no way. He had installed 2 brand new Airtex ones. They thought the first one was bad so they took it back and had them give him another one. After I diagnosed it and found it was a bad pump I called him. I tried to explain to him thats what it was and he wouldn't believe me. I told him if it didn't fix it I would give him the brand new(AC Delco) pump for free and then figure out what was wrong with it.

I have had several other stories similar to that. The straw that broke the camels back was an S-10 Blazer. That was the last attempt at using one and since then I never have.
