This fuel pump fits Chevy Silverado models as advertised and installs without headache. The connectors and mounting points align properly, and the unit drops into place without forcing or modifications. Once installed, fuel delivery is steady and quiet, and the truck starts and runs smoothly without hesitation. Performance feels consistent and dependable, with no noticeable drop in power or efficiency compared to the OEM unit. The construction feels solid, and the pump runs cool with normal electrical load. If you’re replacing a worn or failing fuel pump on a Silverado and want a reliable, straightforward replacement without paying OEM prices, this unit does exactly that.

I got this fuel pump a while back and just installed it a few days ago and it's definitely doing it's job I didn't have to change the electrical connector it was already the right one, it seems like a great product a very well constructed, couldn't really tell the difference between my old fuel pump and this new one I'd recommend this to anyone that would like to save a few bucks

Update: pump started to fail after three years. It was starting hard and missing on acceleration. I bought this pump again because it’s definitely worth the money. I’m very glad I cut the hatch in the bed. Installed the new pump in 15 minutes and it runs strong again. Works perfectly in my 2002, 4.3L, 4x4, regular cab, Silverado with stepside bed. Rusty bolts made me decide to not lift the bed or drop the tank. I got a jigsaw and cut a hatch door in the floor of the bed, above the pump. I measured from below. I soldered the new wiring harness first and wires were obvious. Purple to purple, thick black to thick black, gray to gray, orange/black to thin black. Lock ring came off after a few minutes and some penetrating oil. Truck runs smoother than before. Shop wanted $700+, I did it for $60. I’ll update if it fails.

So far so good.. I Purchased on June 8th, 2025 and got it the next day. I’ve only had it installed for 6 days so far.. Installing went smoothly once I removed bed.. (removed bed completely to do some rust removal and sealing) truck started up 1st try after install. Only thing I don’t like is having to cut harness to use updated plug. No wiring instructions.. hopefully it will last years to come. I will update review later to let people know about longevity..

Works great

I purchased this pump in March 2019. It worked for about five weeks. So I contacted the seller but they did not get back to me. I then contacted Amazon and they replaced it with a new one of the same brand. It worked on and off for about three weeks. And then finally stopped completely. I have confirmed there is power to the plug and I have a good ground but it will not pump. It was a very good price for a pump. But after replacing it twice and now I have to replace it with a different brand for the third time it turns out that is was not such a good price. This is the first time I have reviewed an item. I've read reviews in the past where the person is seething with disgust and it makes them sound like a former employee of the company or something. I'm just telling all you thrifty (tight a--) people like my self, the savings on this fuel pump is not worth the grief. YOUR WELCOME Side note: I called amazon this morning and told them, "I did not want a refund or a replacement pump. I just want them to know what I had been through with this pump and they should not sell it." They told me to write a review, so I did.
