Where is the fuel pump on a 1997 Silverado?

In the fuel tank. ther pump is in the tank you should also replace the pigtail connector as the ground wire in the stock one is usually the cause for the factory pump burning out also, when you buy a new one, i recommend getting a "factory" pump from a dealer, the aftermarket ones are crap and dont last very long, i know this from experience, i replaced mine 3 times in 4 years before i was told by a friend to get the dealer pump, goin strong ever since.(5 years)
