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

This seems to be pretty standard practice in marine applications,
called on-board fuel polishing. See:

[DAY8293A@...]

Well,,, I made my own recycling system using my onboard 2 micron RACOR
filter. I hooked up a T on the output of the RACOR , and a shut-off on
each end of the T. I close off the side going to the engine, and open the other
side, which goes to a regular electric fuel pump (from NAPA, or any parts
store) , and run it back into the tank. I chose to run it back into the neck
where
I drilled and installed a permanent elbow to connect the return line to.
I used clear fuel line,(so I can monitor the pumping), and even put
one of those magnetic things that Algae X claims breaks up the "clumps" of
fuel,, (although not as big a magnet as theirs).
When I am ready to hit the road, I turn off the pump, close the
recirculating side, and open the engine side of the T,,, and hit the road,,, (It
will even draw fuel into the RACOR, if you have changed the filter, and need to
refill it)
And it cost me a lot less than some of those systems I saw on those
links,,, Less than fifty bucks, anyway. I was using the larger micron filters,
until today, when I got a case of 12 of the 2 micron filters.(for $7.02 each,,
under 95 bucks with shipping) Since I don't hit the road too many times a
year, I need to keep the fuel circulating.
I had a real problem with algae in my tank before I installed this,,,
and it has really cleaned up my fuel,,, along with some good algae eater
stuff. Wish I had installed it and filtered the tank before I went on my first
outing with my bird,,, boy, I can't remember how many filters I went through on
that first trip!! Now, I can hit the road without worrying about clogged
filters,,,, DAY 83 PT-40 JAX FLA,,,
