For 100'ish shipped it's a direct replacement for the existing fuel pump. It's a good reliable upgrade/replacement.

really? ok ill pump that in once i get my tax refund. this knocking is out of control now though. like i cant even though the gas without it detonating. i am gonna try and do a leak down test to see if the rings are bad. also who has a coolant system compression checker for my truck? the ones at autozone dont fit my radiator cap. any ideas on what this might be? also this might just be me but my oil pressure is at about 60 when cold @ idle then drops to 50 when warm. then when driving and warm it jumps to about 65. weird right? my brother said failing crank bearings might be the cause of knocking AND high oil pressure.
