<VV> looking to buy a spare fuel pump

[Frank DuVal]

I do not remember anything about the heads of the screws being a "tell" 
for a bad pump.

There was a time the rubber diaphragms of the pump were made from 
inferior material. You could tell those pumps as there was no visible 
fabric when you looked at the edge of the diaphragms. Compare several 
and see if any have just plain black rubber instead of the fabric 
reinforced style.

I have had to retighten the screws on pumps to cure leaking that starts 
after installation. Some people retighten them right after installation.

There should be a tag with 4886 or such hanging off one screw besides 
the made in USA stamp on the top cover.

It is amazing how many sources of this pump are still around:

My most recent purchases were from John Sweet in Pennsylvania.

I would use that pump you already have, when you need one. Then buy 
another spare to sit on the shelf.
