I've got a feeling my fuel pump's on its way out, the car hesitates and stumbles pretty bad when i quickly accelerate. I've seen about the Blazer fuel pump from a 95 or so, how well would that hold up with the GM S/C for the 2.4? Also I saw something about an adjustable FPR might be needed as well? I just replaced the FPR not too long ago thinking it was bad, but that didnt fix the issue i had at the time.
