the fuel pump for my 2002 cavalier was easy to order, came a day early with free shipping and was a 3rd of the price that the local auto parts places want...5 stars.

Highly recommend!
Was skeptical about buying a fuel pump that wasn’t $200+ like the rest but this pump has been installed for about 3 months now and works like a charm! Installation wasn’t hard either, learned that you have to use the thicker o-ring for it to work. Works great and car has never ran better

Worked like a charm!
I ordered this fuel pump for my husband's 2005 Pontiac Sunfire. The part was super easy to order and super easy to install with the help of the Installation video by 1AAuto. When I ordered the part there was also a list of tools I would need so I could get everything together before crawling under the car, which saved loads of time looking for this tool or that tool! I would order this part again and recommend it for others! I plan on ordering a few more parts for my Tahoe too.

DID NOT RUN This pump did not work at all
I will never buy anything from this site again the pump was installed correctly and double checked by a mechanic and would still not run. I had to install the old pump I was updating. I am currently trying to get ahold of customer support and get my money back for this piece of junk part.

Fuel pump for Alero
The unit arrived very quickly and was installed perfectly in our Olds Alero. All that was needed was a full tank of gas to balance the float.

Fuel pump
Works great, been having for a few days. Easy to install, color match all the wires and you shouldn't have a problem. Just make sure to at least put 8 gallons in order to see the fuel gauge move up of not it will show like it's empty.

can you put an in line to bypass pump in tank?
carl e on Feb 27, 2016
BEST ANSWER: They may make some sort of in line pump but this isn't the one. However, I installed this pump in a 2001 Pontiac Grand Prix and it was pretty easy. There was a metal cover in trunk just behind the back seat that gave easy access to fuel pump.
Does it come with a fuel pressure regulator ?
Walter damon N on Aug 26, 2018
BEST ANSWER: No, you would have to buy that separately
