<VV> need help diagnosing fuel problem

[J R Read_HML]

There are 2 short rubber sections in the fuel line.  They could be blocked 
or simply have an air leak.  The pump will NOT pump air.

You can put a stick into the filler neck, down into the tank and see if it 
comes up wet with fuel if you are unsure about that.  Or jiggle the whole 
car and see if you can hear the fuel slosh.

Replace the two hoses - one at the tank and one near the LR wheel.  See if 
you can prime the pump.  Loosen the tapered bolt that holds it in place and 
pump it up and down a dozen or 2 times.  You probably need to do this enough 
to fill the carburetor bowls at this point.  Make sure the bolt is centered 
in the detent on the pump when you tighten it up again.

If you are still not getting fuel, then the blockage is likely the strainer 
"sock" inside the gas tank.  You'll need to drain the tank, which you can do 
from the hose under the tank, and then remove the sending unit (special tool 
for that but can often be done without it).  With the sending unit out, 
check the condition of the tank for garbage, rust, etc.  You just might need 
to take the tank out of the car, clean and seal it and put it back in.* see 
below   Replace the sock and put everything back together.  I think there is 
a gasket for the sending unit, so you want to have a new one handy.

*If the tank needs to come out, let us know and we can give some tips on 
that.

The car last ran 6 months ago, battery was dead.  Replaced battery and 
cranked... no fuel.

Disconnected fuel line at carb.. no fuel

Disconnected fuel line under car (before fuel pump) and it was dry....

Cranked car with my finger over the fuel pump end of the fuel line.. no 
noticeable vacuum (should there be vacuum from the dry fuel pump while 
cranking?

Just out of gas?  Not likely, but possible if the fuel tank was leaking 
slowly without anyone's knowledge.. guage reads 3/4 and is correct as far as 
anyone knows.





So what do you think?  Where should I start?  This is a 110 Monza, I have a 
140 Corsa I can steal parts off of to diagnose if neccesary.
