Review on Enhance Engine Performance with GM Genuine Parts MU1738 Fuel Pump, Level Sensor Module, Seal, and Float by Shaun Stapp

Revain says the product fits my 2003 Chevy Suburban. Drained and dropped the tank and fitted a new pump only to see that it had a flat port while the original had a square port. My Suburban has a Z in the 8th digit of the VIN. Nothing that I know of identifies it as flex fuel or with an upgraded option. Now I'm looking for an adapter or a new plug to connect. It takes some pretty nasty work (dropping a full tank to get to the fuel pump) and became a challenge. I would like to return this item to an auto parts store and compare to what I really need, but I bought it online. It would be helpful if this part was sold with an adapter or cable connector. Or at least if the product description says which plug or adapter is needed. I recommend anyone doing this repair to remove the tank and see what fitting and fuel pump you need before ordering this part.
