Year : 2000
Make : Chevrolet
Model : Z-71 LT
Engine : 5.3L vortec
MAF indicator, fuel filter. Password/security reset, pressure test-50PSI
The fuel pressure specification for this vehicle is 55-62 psi. The pump is on the weak side of the spectrum so it is a place to start. The pressure is under the specification.
so just go ahead and replace it? recomendation for kind? and I have a full tank of gas but if I can take off by bed can i access it from the top?
