Fuel Pump Question

cmcelroy09 · 04-26-2009, 11:28 PM

Ok i know this may be a dumb question but here goes, I just got done changing my fuel pump in my 96 blazer. Are supposed to be heard running at all times? I don't remember hearing my old pump running all the time.

Did you replace your fuel filter at the same time?

cmcelroy09 · 04-26-2009, 11:50 PM

I replaced it three days ago and I did the pump about an hour ago.

Could be a few factors...A. you don't have the O-ring or the clip in all the way or seated correctly? Newer stronger pump maybe? Did you use a cheap 200.00 pump or the Delphi one? Do you have the right fuel pump? There is a difference in the 2 dr and 4 door pumps and when you got the new pump did you get an updated pig tail end?

Well thats a fuel pumps job to run constantly..reason i asked about the connector end is maybe by chance it got wired up wrong..since you have to splice a new one one

Had two different ones on mine, could always hear them. Not super loud, but if you're listening for it, you can hear it.

My fuel pump became noticeably loud only after I changed the fuel filter. Before, I would have to be outside, near the rear of the truck to hear it. Now I can hear it inside...

Maybe there's a link?

Some pumps are just louder.. also depending on how full or empty your tank is it can echo a little inside the tank..
