New option for fuel pump replacement

[mhobtr]

I started suspecting my fuel pumps as a source of sluggish acceleration.

I pulled the pump assembly and was not pleased with the hack job someone had done on replacing the two pumps so I ordered a complete new ACDelco assembly thinking that would solve everything.

I didn't do my homework as I should so I didn't replace the plastic hose clamps and, not knowing any better, I didn't check the backflow check valves in the pumps.

Pressure checked good at idle but performance was not what I expected. I ruled out the pumps because they were new and looked elsewhere but eventually came back to suspecting the pumps. By then I was kicking myself for not replacing the plastic hose clamps so I pulled the assembly and found that the check valves on both pumps were bad.

I bought two new Delphi pumps from Rock Auto, with good check valves, installed them along with new stainless steel hose camps and I am very pleased with the results.
