Review: Great price and fit my Avalanche perfectly - I cut an access panel under my back seat of my Avalanche. That made the install so easy. Dropping the fuel tank is a task, as I have done that before. I sealed the hatch, put the carpet back in place and you can’t tell anything was done. It sure made installing the fuel pump a breeze. Fuel pump does everything it is supposed to do and my truck runs great.
Review: Perfect fit for my 2003 Avalanche Z66 1500 at a great price! - Perfect fit for my 2003 Chevy Avalanche 1500 The only thing is the rubber seal that comes with it is thicker than the factory seal and makes it a somewhat difficult to seat the pump down so I ended up using the rubber seal from the bad pump and it went right in with no issues. Didnt need to use or mess with the harness plug that comes with it as it was simple plug in with no problems. As far as I'm concerned it's a good product at a good price. Started right up first turn.

### ⭐⭐⭐⭐⭐ Perfect fit for my 2003 Avalanche Z66 1500 at a great price!

### ⭐⭐⭐⭐⭐ 2002 Chevy Avalanche Z71 Fits
*by L***S on December 7, 2020*

Ordered this back in Aug 2020. 2002 Chevy Avalanche Z71. 5.3L. Local price was for a fuel pump was a couple hundred. I was very hesitant about ordering this, based on price and some of the reviews. Most of the bad reviews seemed to be electrial issues. Before I installed I did look over the wiring and compare to the existing unit. The only wires that did not match up were the wires to the pressure sensor. I dont know if it would of made a difference if I didnt switch them, but I ended up moving the wires to match how they were on my existing worn out unit. Fit with no issues. Did not need to use the adapter that was sent with it. So far, working like it should. I have about 1700 miles in it.
