Hello All, I'm having an issue with my 04 Silverado 1500. As of late, it has had a SERIOUS decrease in power(especially while driving uphill, trying to overtake, or towing/hauling) I have a sneaking suspicion it's related to the fuel pump/ fuel filter. My question to you is this: what similar years models could I take the in tank fuel pump assembly from and swap into my 04? I've been looking at local salvage yards and need a wider range or year models I could potentially take from. Any help would be greatly appreciated!
