Question about 1999 GMC Sierra 3500
If it is gas you will need to buy the fuel pump from the factory or from your local GM dealer, I do not recommend aftermarket pumps as they tend to fail after a short period of time. also replace the fuel sock and fuel filter at the same time, this is called preventative maintenance and will save you problems in the future.
