So, cheap pump we bought seems to have gone out already, was giving worse than crappy mileage and at quarter tank would act up or stall. Been looking into getting a pricier pump not a cheap one like before. Been reading and seen that the AC Delco, Delphi, or GM are best to replace with. But haven’t seen a ac delco I for a 4 door on rock auto, but seen Delphi has two different ones for the 4 door one with and one without check valve, how do I determine if my has this?

 

Some of the online GM parts sellers allow you to enter in your VIN for their search which should give you the part number you need. You might try that.

 

You happen to have a link to a recomended GM parts seller?

Thanks

 

RockAuto has GM pumps

 

Have had Delphi pump only last couple years. Most of the these pumps look similar. Probably only 2 or 3 manufactures make all the pumps for everybody. Think its a case of bad luck. I put a Chinese knock off in my Ford pickup with a 460, as couldn't wait for a good pump as were were on vacation pulling our trailer. Its been running great for years.
