<VV> U can lead a vair to gas but Can't make it drink

[N. Joseph Potts]

There's a cam under the pushrod (that's its name) that makes it go up, but
it may not go back down unless something pushes it back down. If something
does, then it will reciprocate as designed. The pushrod CAN be too short
from wear, but that's unusual (and hard to discern) and the cam can get
rounded, but that's even MORE unusual. There is supposed to be a spring
perched atop the pushrod. If the spring isn't in place, the pushrod may not
go back down again. It's also possible you haven't pushed the fuel pump down
as far as it's supposed to be when you install it. Look at the side of the
tube under the pump. You'll see a dimple in it. Now look at the hole you put
that tube into (on the engine). You'll see a pointed screw going into that
hole from the side. The point of that screw is supposed to go into that
dimple. It's not hard to get once you're looking (feeling) for it.
     People who give up on this original factory mechanical pump system get
around it by installing electric fuel pumps. These are not expensive, nor
difficult to install, but they can be noisy, and if a float valve ever fails
on one of your carburetors, you can get into real trouble (hydrolock). I've
seen this on one Corvair.
     I use the mechanical system. Once you get it going, it goes and goes.

PS  You craft a great subject line. You must be very creative, perhaps with
words?

  Hey All,
After tightening the cap of the fuel pump and pour gas through a funnel into
the inlet it didn't leak. But I'm still not getting gas to the carbs.  I am
beginning to think it's an under the pump thingy.  I may be using the wrong
wordage so bare with me.  The thing I'm gonna call a push rod (yeah that
sounds right to me) went up one time and stayed there when the engine is
cranked.  Is that the way this thingy is suppose to work or would it be
moving up & down continuously?  I seem to be yet again at a road block.  My
fuel lines from the pump to the carbs are clear (remember I broke the old
set) and I ran a hose from the inlet to a gas can (8" line with hose
attached...clear) and still nothing. Suggestion, comments & mechanics that
work for food welcome.
