Same here.   If you use the CORRECT mechanical fuel pump you can 
expect it to last decades.   The Vairs here ALL have mechanical pumps 
and there's been no issues at all outside one pump about 8 years ago 
which had the bogus non-fiber reinforced rubber diaphragms which 
failed within a week if its having been purchased.   THAT pump 
slipped by me.   Honest vendor replaced it with the correct material 
pump which has run on and on ever since, never a problem.

Likewise the pump that's on the engine in my '60 4-door.   That pump 
is almost 41 years old and still works fine.



If you use the correct mechanical pump, there will be no 
problems.    Unfortunately there are still a few of those bogus pumps 
floating around, and they tend fail quickly.

Don't blame the design for the failures.   Make sure the mechanical 
pump you put on the engine is the right one, and *then* make sure you 
follow the standard instructions (snug the screws after a few days 
running) on adjustments after you install it.   There's no reason to 
assume that a correct mechanical pump is inferior to the electric 
pumps... and in fact in many cases it's the electric pumps that can 
be troublemakers, not the mechanical pumps.




...whoever it was that decided to use non-reinforced rubber gasket 
sheet as diaphragm material in fuel pumps needs to be hunted down and 
shot on sight, and it wasn't just 'Vair pumps that got this bogus 
diaphragm material either.
