Also,  this bogus diaphragm material that got used by some  
rebuilder/manufacturers was NOT restricted to just Corvair  
pumps.   It ended up in other reman'ed and repro pumps as  
well.  We're not the only ones who complain about replacement leaky  
fuel pumps.   I know a guy with an older Cadillac who went  through 3 
pumps before he finally found an original manufacturer's part  with 
the right diaphragm material.   Likewise a fuel pump that  was bought 
for my brother's "Fiat 127" (don't wanna say Yugo in here for  fear of 
ridicule) which used that SAME crappy rubber.  That pump was  returned 
for credit, the original, which was disassemble'able, got taken  apart 
and fixed on my bench, afterwards, no more  problems.



Tony makes an important point here.  Even though I am seriously  looking at 
an electrical pump conversion for my Corvairs I know Corvair  mechanical 
pumps are not alone in having a bad reputation--all replacement pumps  for 
vehicles with mechanical fuel pumps seem to have a high failure rate.   The new 
mechanical fuel pump I put on my mother's Celebrity a few years back  
started leaking fuel by the time she drove it the 1200 miles to Florida.   So I'm 
not suspicious of just Corvair pumps--I look at them all with suspicion  
now.  The ones we had in the '60's and 70's weren't perfect and wouldn't go  
over 150K like the new electrical ones do, but the old ones sure as heck 
didn't  fail in less than 5K miles.
