Fuel Delivery Problem

Could be the fuel pump push rod is worn. Some one might know the proper length here.

Posted a request for the proper pushrod length a while back, got a lot of don't know's and never thought to check's, which is understandable. Can't find it published anywhere either. Did hear that the new ones you can buy are about as good as everything else coming out of China these days though. Maybe someone who does know will chime in this time around.
