It is a bit like the EM vs LM "debate".  I've always used the stock style 
mechanical pumps.  There was a bad run of them about 20 years ago and they 
ended up with a bad rep as a result and it then became popular to install 
electric pumps (which can also fail).  The thing is, once a mechanical pump 
dries out (if it was an older one) it can develop leaks as the rubber cannot 
stand up to the modern gas once the gas is gone.  If kept wet with gas, even 
the older ones will be fine.  Newer mechanical pumps contain a material 
which does not seem to suffer that malady.

You could take a look in the carb bowls and see if any black (probably 
rubber) particles are present.  If so, they could be from the pump or from 
the accelerator pump cups - which can also suffer if allowed to dry out.  If 
not, you are probably fine and just need to prime the pump enough to fill 
the bowls (if not already full).

Oh, how old is your gas?  You may need to source your gas from a can of 
fresh stuff.

Later, JR
