Fuel Pump - What is a good brand for replacement? - update

[1990 Pioneer 4x4]

IT appears my fuel pump has finally died after 20 years, or at least I think so... It's was losing power on my last trip home; as it felt like it wasn't getting enough gas and wasn't making it's usually loud noise.

 

What brands, what should I be looking for in a quality replacement? Yes, I’ve read through a few of the older pump threads, but didn't find an answer to my question. :help: THANKS

OK, i guess these are my (O'Reilly's) choices:

 

Ait Tech $81.99

Bosch $99.99 + $20 ship

Del Fhi $101.95

 

Is one really any better than the others? :help:

I used the Bosch from Napa for my 91, it has been in since March and works great. I don't know abou the RENIX pumps, but for the HO the Bosch was much smaller than the pump it replaced, but still performed as good as the old pump.

Apparently there was two pumps that were installed in the ’90, the Bosch and Walbro. How do you know which one will fit with the other stuff prior to opening it up and looking? :dunno:

I have changed my twice now since the factory unit went... I think bite the bullet and replace the next one with a factory pump.

What "factory part"? The service guy at the Jeep dealership said there wasn't one. I'm confused.

I would either do a delphi or bosch... Or obviously OE

Thanks - I definitely need new people. Glad I got you and the other CC folks. Still confused why multiple people (part stores) said there were two types of pumps used for the ’90. :huh???:

I have herd this too, the last time I just took both and used the correct one and returned the other. I cannot remember the differences. Could be 4cyl/6cyl. Some applications in the parts books are vague in the after market.

 

My complaint as well as the OP's I'm guessing. Is the longevity of the pumps. They simply do not last. Its not a awful job in the MJ, but its no walk in the park. Considering the stock pump usually lasts twenty + years and the aftermarket crap usually doesn't make it to its 2 or 3 birthday. That's not so good... The aftermarket pumps are about 75- 100$ and the stocker is almost 400$ its not a surprise most go with the aftermarket. Especially seeing a name like BOSCH as the manufacturer. But its a false sense of security, these pumps simply do not last like the NOS parts.

If you have the option of getting an Airtex, don't.

The OEM fuel pump is now “DISCONTINUED”. Looks like all YOU have to choose from is the aftermarket pumps. I just found the LAST two (2) OEM Pumps, one in CA and the other was in NY, and yes I bought one!

 

Thanks for all the feedback!

CW,

 

for me your link shows an option for a 2.5L, 4.2L, or a 5.9L :doh:

[CWLONGSHOT]

Cracker,

At this page, on the left, click fuel system. Then fuel supply and finally fuel pump. This will get you a 2.5, 4.0, 4.2 and a 5.9l pumps.

The thing is they are all listed under a 1990 Jeep Comanche??? :???:
