<VV> Electric Fuel Pumps vs Diaphragm

[Ron]

But, when an engine hasn't been run for a long time, you don't want it to 
start immediately!  Ten or fifteen seconds of cranking while the carburetors 
fill up will also bring up the oil pressure and oil all of the bearings. 
I've noticed that the oil pressure light goes off before the engine starts 
on those occasions.  It appears that all problems are solved by using the 
stock pump.  Of course, some people have an unexplained compulsion to spend 
money on something and I suppose electric fuel pumps are as good as cigars 
or jewelry.
