Excellent Customer Service
Alright, first fuel pump was delivered and the metal contact on the float was damaged. Here we go I thought, so I call them up and i couldn't believe what happened. A entire new part was sent out immediately with expedited shipping and arrived 2 days later. I wasn't required to ship back the old part, they told me to keep it. What! Anyways, part fixed my hard starting under a half tank of gas issue and only complaint is the electrical connector was a super tight fit. I will certainly be buying from these guys again.

So far so good.
I only bought this a few months ago and so far so good. I have bought several items for a variety of car that I work on for my family. Everything is well priced and typically all beats your local auto parts store. However, I have had to return one item due to manufacture defect, and if you want to continue the lifetime warranty you have to pay to ship the defected item back. I’m not sure if it’s just me but I’m not used to paying to return items. I guess that’s because I always shop Amazon. Other than that 1aauto has quality parts for a reasonable price, and if you’re not worried about getting your hands dirty they also have helpful videos to walk you through installing it yourself.

Wrong
I would really like it if I was sent the right fuel pump that attached to my wire harness on my 2002 Chevy Suburban 4x4 Flex Fuel truck and the fuel pump worked. I even looked for other wire harnesses to fit the pump to get it to work and there's no wire harness to fit it'

Who's this fuel pump made by?
Randy on Feb 17, 2016
BEST ANSWER: These are a 1A Auto house branded item. They are made overseas as pretty much ANY part today. We can't really escape this however these carry a lifetime warranty. We could not put a warranty on this if we didn't feel it was a quality item.
