How to change fuel filter in 1999 Chevrolet Tahoe
it is in the fuel tank
It is inside of the gas tank. You will have to remove the tank to service the fuel pump. From someone who has replaced 2 fuel pumps. The 1999 Tahoe needs a GM fuel pump. The after market fuel pumps don't work. Something about not pulling enough volume I think. After I replaced with the GM fuel pump, the car worked great.
It has an electric fuel pump inside of the fuel tank and if it has never been replaced then it will be a A/C DELCO pump and if your smart you will put the factory pump back in it.
