Performances issues with replacement fuel pumps.
All, My question is, has any one had performance issues when they replaced their fuels pumps used in the Chevrolet Suburban? A friend of mine had his fuel pumps changed at a Chevrolet Dealer in Portland Oregon & his ZR1 has performance issues.

Re: Performances issues with replacement fuel pumps.
If they didn't change the sock? Also, it may be injectors

Re: Performances issues with replacement fuel pumps.
Big block fuel pumps have an operating pressure of 65#-95#. ZR1 pumps have an operating pressure of 45#-65# - Might cause a problem.
