there's nothing wrong with the mechanical pump as designed
Bill
Except for the fact that most of them have a rubber diaphram that cannot hold up to today's modern alcohol/methanol/oxygenated fuels which rapidly dry the pump diaphram out ,resulting in fuel leaks that dump raw fuel into the engine crankcase which dilutes the engine oil and results in fried main bearings and burnt cam shafts.
I am all done with those crappy original style mechanical fuel pumps.
Here is the way to update to a high quality electric fuel pump.
