5.0 out of 5 stars Perfect fit!!
Reviewed in the United States on March 11, 2012

I installed this fuel pump in a 2002 Olds Aurora. The biggest problem was getting the old one out. I used some penetrating oil (a couple days before) on the locking ring before I attempted to move it. Use a brss rod (no spark) and a hammer and hit it on one side and then the other (counterclockwise) Soon it will began to move. Grease the locking ring when you re-install it and it goes on much easier. I did have to change the one connection (that is supplied) to match the connection on the pump. They give you barrel connectors to spice the wires-----I soldered the wires instead using an ELECTRIC soldering gun. All the directions were very good! KEEP THE OLD CONNECTOR IN CASE YOU BREAK DOWN SOMEWHERE AND THE PUMP THAT IS AVAIABLE HAS THE OLD STYLE CONNECTION ON IT! PUT IT UNDER THE SPARE TIRE!! YOU NEVER KNOW!!!

4.0 out of 5 stars Almost flawless...
Reviewed in the United States on December 10, 2016
Verified Purchase
The fuel pump works flawlessly, I no longer have a surge on heavy acceleration, no more whine from the tank, and no more intermittent extended crank times, although I am disappointed that the fuel sender for the gauge does not indicate a full tank when I top it off. It's a nuisance that I will live with as I will not go back into the tank to try and adjust (bend) the float rod. I would have given 5 stars if the gauge would indicate full, at most it will read about 7/8ths full. I guess the most important thing about the sender is that it does indicate when I'm getting close to empty.
