Changing my fuel pump in the a.m.,,,
On my 2000 Blazer,, it was running a bit poorly and my fuel pressure was off by 10 psi,, at 54 psi,, so I am putting in a Delphi unit from NAPA,, I should of took some pics before I started,, and living in salt city central Ohio,, it was fun,, had a hard time getting to the fuel lines to disconnect them,, the middle one was a bear,, but got it off. I have a trailer hitch that was rusty,, go figure,, so I took it off to blast and repaint. One of my issues is that if I drive for a bit, stop come back out restart the Blazer it ran like crap,, no power then a minute or two later,, it took off and ran OK not great but better,, so once I put in the new pump & filter I will post up and let you know how it runs,, Thanks to all so far have helped me with this truck!!

THANK YOU for buying oem and not a off brand. your blazer will love you for it dearly.

AMEN!!!!!! I have tried the Master pumps and other junk,, you always do it again,, OEM rocks!! Matty man

Update;; Swapped the pump out and it runs so much better,, started it stopped, let it set for a bit started and drove off and no performance issues, but,, I may have a faulty gauge,, put on my gauge and it shows again 54 psi,, and now the pressure bleeds off right away now,, a few months ago it held steady after shut down,, and there is a flutter in the gauge while it is running,, so I am wondering if the pressure regulator is now need of replacement?? I replaced the fuel filter as well,, I am going to use a snap on gauge to double check the pressure and flutter if any,, but the pump needed swapped out and it runs so much better,, any suggestion?? Thanks matty man

try testing it with a different gauge
glad someone decided to put an oem part good choice my friend |
if the pressure drops right off then it sounds like the regulator is leaking or the check valve in the tank is bad.
