<VV> Fuel Pump?

[Rodney Spooner]

To test your fuel pump, may I first suggest pulling your (engine oil)
dipstick out to see if it smells of gasoline. If it does then there's a good
chance that the diaphragm in your fuel pump is ruptured. If you want to keep
your car "stock" then I recommend replacing the fuel pump with a new one.
They can be rebuilt, but for the time, cost, warranty, and peace of mind,
replace it with a new one. Otherwise I highly recommend installing an
electric fuel pump as close behind the fuel tank as practical. They are much
more reliable and should give you many miles of trouble free Corvair
cruising. You can use a fuel pump plug and do away with the mechanical pump
all together or with a relatively simple modification you can even retain
the mechanical fuel pump and keep the "original look". There is a boatload
of information available on how to do that.

Otherwise, if there is NO GASOLINE SMELL on your (engine oil) dipstick:
1. Make sure there is gasoline in the gas tank.
2. Jack the front of your Corvair up so wheels are off the ground.
(Alternate: If the front of your Corvair is lower than the rear you can us a
compressor to slightly pressurize the gas tank (5-7lbs. s/b OK) AFTER
FOLLOWING STEPS 3-5.)
3. Remove gas cap
4. Remove the air cleaner assembly.
5. Slightly loosen (with appropriate size "Line Wrench") all 3 fuel lines at
the fuel pump. (Alternate: Slightly pressurize gas tank then go to step 8.)
6. Loosen fuel pump lock nut and remove retaining screw (at base of fuel
pump). The fuel pump should pop up a smidge upon doing this procedure.
7. Slightly press down and release the fuel pump several times.
8. Check to see if the fuel line connections at the pump are wet. If
everything is functioning properly they should be after only several pumps.
9. If yes, then proceed to step 11.
10. If not, then repeat steps 7-8 a few more times. If the fuel line
connections get wet continue to step 11. If not, then I would conclude that
you have A) a fuel line blockage somewhere upstream, or B) a faulty fuel
pump.
11. Tighten fuel line connections at the fuel pump and loosen fuel line nuts
at the carburetors. Repeat steps 7-8 then continue to step 12.
12. Tighten the fuel line connections at the carburetor.
13. Slightly press down and release the fuel pump a few more times to fill
the carburetor bowls with gasoline.
14. Look down the barrel of the left (driver's side) carburetor and push
down on the accelerator linkage to see if gas is being jetted into the
carburetor venturi.
15. Repeat for right side carburetor.
16. If no gas is being jetted in to the venturi then you have a problem with
fuel delivery in your carburetor.

Hope this helps.
