Review on Delphi FG0324 Fuel Pump Module by Brandon Skeet

The cheapest and best opportunity to get the original. If you get a lean code 1 and/or 2, check the fuel pressure first. Standard GM trucks need to be 55 to 62 psi under load. Mine was at 45psi. Don't forget to replace the fuel filter with an AC DELCO and a fuel pump trim ring (it costs less than $4). Most importantly, I drain all remaining gas from the tank and have someone with thin hands reach into the tank and remove any deposits as this is the number one reason a clogged fuel filter causes the pump to fail. If you don't take this step, you may be doing it again very soon. Don't use vacuum or compressed air because you want to be fiddling with fuel and you don't want to build up static electricity.
