80 bird with 3208 cat keeps stalling - PLEASE help

[woodland_builders]

There is a small valve in the center towards the front of the engine
on the top near the injector pump that must be open to allow a fuel
flow path when using the hand pump. Empty your water seperator,
(square glass thing on the right rear of the engine) and reinstall.
Open the vent valve. Using the hand pump you should see the fuel fill
the water seperator and then produce a steady solid stream of fuel
discharging under the engine. If you cannot refill the water
seperator you have a fuel restriction or a air leak some place
between the engine and the fuel tank. Add the aux tank into the
system a try again to locate the problem.
If you are able to refill the system with the hand pump you are
getting fuel to the engine. Shut the vent valve. Try to start the
engine. If it does not start have another person pump the hand pump
while you try to start the engine and see if it lights off. If the
engine starts but does not idle and the problem may be the shaft seal
on the injector pump leaking in air. If the shaft seal is bad it may
run at high RPM but will not idle. If you look down under the intake
with a flashlight and notice a fuel trail from under the injector
pump you have found a problem. Fuel leaking out can also be air
leaking in. Good luck
