[FC] Repairing Fuel Pumps

:...if it's leaking from around the 'sandwich' of parts, you can 
snug  the screws down to stop it..."  
 
I own three Corvairs; one is a van. The van has a  propensity to leak from 
around the sandwich" parts. While a proponent of buying  from the Corvair 
vendors, I've found their pumps to be consistent leakers. I've  reported the 
problem, but with no relief. As a result I've gone to purchasing my  Corvair fuel 
pumps from NAPA (part number: M3988); their pump is new (not  remanufactured), 
has the internal damn designed to minimize fuel leakage into  the crankcase in 
event of a diaphragm failure; their pumps are made in USA by  Federal Mogul, 
and do NOT have a propensity to leak... been using for the past  two years with 
good results. A tip: if using a pump that you are having to  continually 
tighten the screws to stop leaking, add thread inserts (i.e.:  timeserts) into the 
bottom casting: the pot metal threads give  (deform) too much for consistent, 
reliable thread grip.
