IF the fuel pump diaphragm material is stretched out. Would this hamper the performance of the engine say 200 or so lower rpm or ruff idol.

Re: Fuel pump rebuild

Normally if the diaghram is stretched out it will not pump enough fuel at high RPM, and could cause issues, like stalling or lean running. Idle would usually not be affected
