help I don't know how to pick right fuel pump I have a 99 4 -door Chevy blazer I've been through every truck in pick n pull and I've had a problem with each one I'm going to order online but I don't know how to make sure it's the right one

 

I used Rockauto. If you just fill in the info, they will give you a few choices. I put an acdelco unit in mine. Everyone says that's the best pick for reliability.
Oh, that's rockauto.com btw...

 

Get a "Delphi FG0052 Fuel Pump Module" from amazon. It looks like there is only one pump left for sale there on amazon. Mines been in for 4 years...works great. Look at my review of the pump on amazon ... ...... My review is the only one that includes photos, so you can't miss it. I'm not a verified purchaser on the amazon page cause my brother ordered the pump for me. So you can click on the "customer images" section on the right side of the written reviews section, and when the images open, you can click on my amazon user name and get to my review from there.

 

Only use ACdelco or Delphi. Stay away from brands like airtex or driveworks unless you like replacing them on a regular basis.
