Worked great in my 2005 Tahoe.
Was almost identical to the original pump in my 2005 Chevrolet Tahoe. The fuel lever sender was positioned to the side rather than the back of the pump but the entire assembly fit in fine and works great. This was an original equipment pump in AC Delco packaging. It was manufactured by Bosh. This came with the large seal that goes between the pump and the tank. My original pump didn't actually quit but the lines rusted out and then leaked. This pump was a great deal.

Yuuuuuup hella want this pump.
Lol I learned the hard way. Always go OEM. This works good. Got a cheap one from here for a fraction of the price and the crap stopped working and had me and my family stranded. I found out that Gieco insurance is not what you want when it comes to emergency road service. Lol got triple A and they towed me on the spot. So yeah this one is good. Been working since.

Came Damaged
This is a so called GM OEM pump. It did not match my original pump but would still work if it didn't come with a internal broken part. Pump was installed months after purchase so I'm out $230 plus all the days off work and shop diagnosis and install of a new pump.

Put it in an 05 Tahoe. Fit perfectly and performance is factory quality. Just as quiet as the original too. Definitely worth the money. Delivery and condition of the packaging was top notch as always.

Decent quality
Great quality fuel pump for the same price as an aftermarket delivered to your door! No issues and don't forget to order the steel retainer if you live north of the salt belt. I do wish ACDelco would coat the exposed steel lines with a material that would not rust.
