So for an older GM 5.7L engine, does the fuel pump push rod wear? They stock them at NAPA so someone must be buying them due to wear or damage. These are engines around 1985.
Yet it looks like a heavy duty chunk of steel.
Why do people (or why did they) replace them, do they become shorter or get all mashed up?
(I had thought about asking this question before but could not remember if I did.)
