<VV> fuel pump issue

[Garry Parsley]

Thanks Joel,

That sounds like a good way to prime the pump. I'll give that a try. Any 
chance of pushing too hard (or far) and rupturing the diaphragm?

If you have fuel at the pump you can remove the pump mount screw and pump it 
manually to see what happens.  That should eliminate the length issues and 
you can feel fuel in the pump when it starts to work.

Subject: <VV> fuel pump issue

Hey gang,

After 8 months of work I’m finally at the start it and adjust stage on my 66 
Monza, but am still having an issue. When I put a little gas in each carb, 
it fires right up, then dies. A definite lack of fuel issue. The original 
pump was leaking, so I ordered a new one. While waiting for it, I read the 
tech guide articles about the wrong length stem coming out of the pump on 
the newer versions.  The original pump was 1/4” long, so I checked the push 
rod. It wouldn’t come out, so I ended up removing the rear housing, and 
found the end of the rod mangled. The “too long” shaft now made sense. Have 
now replaced the sending unit, hoses, fuel pump, push rod, eccentric. The 
new pump’s shaft was 9/32” long, so I cut it down to 7/32” but it hasn’t 
helped. I’ve verified fuel to the pump, but when I crack the lines at the 
carbs and crank it – dry. My question is – is it possible the rod in the 
pump is still too long at 7/32” sticking out? Could this be keeping the 
diaphragms from doing their job?  I didn’t want to risk cutting too much 
off, but will listen to all suggestions. I fear I may have tunnel-vision at 
this point, and would appreciate some input.
