I'm replacing the fuel pump in my 94 s10 blazer vin W, just curious what brand yall recommend and if i should replaced just the pump or the whole assembly.

 

I would say whole unit and go to NAPA to get it.

 

Everyone says Delco. I replaced mine with a Dorman and haven't had any problems so far. New fuel filter is in order here too you know as well as a new pick up screen. Make sure they give you the right pump as a Code W engine takes 55 - 61 PSI to function properly and the sometimes the guy will give you one for a Code Z engine (16 -20 PSI).

 

thanks for the response, i cant find delco at any of the parts stores here, advanced/auto zone/napa, is that a dealership item?

 

Napa usually has quality replacement parts for Chevy's

 

AC Delco or Delphi. That's it....

 

Yes double check they give you the correct pump for your engine type. The wrong pump and you wont get enough pressure to start it.

 

I got a Delphi pump for mine. Works great and puts out the right pressure. It is alot noisier than the old one, but thats good, I know its working. I did the tank, sending unit, and pump in mine, was about $400 total I think.

 

If you havent found a pump yet, check out Summit Racing.com I saw that they have AC Delco pumps.

 

Put an NAPA pump in mine a few years back, had it go bad at 3 months, and was on a road trip at the time. Napa replaced the pump under warranty, but it cost me a day in the garage of a small town and $300 in labor, plus a motel room. A year and a half later it quit again. Local garage guru said it was needing a Delco. He had one in stock. Charged $150 for the pump installed. No problems for two years.
