There is a filter screen in the tank, but there's no easy way to check or
change it. First thing is to ascertain if you indeed have a fuel delivery
problem. First thing I would do would be to check pressure while the symptom
is occurring. Fuel pressure should be 30-40 psi (higher under load). You
need a fuel pressure gauge (any pressure gauge that will measure 0-60 psi
will do, if you can get it securely attached via some 7mm fuel hose to the
test fitting below the pressure regulator. This is just in front of the
ignition distributor...)

                            CAUTIONARY TALE:
Does this happen with a full tank of gas? Does it seem to run out of fuel
before it should? We once had a weird problem like this and found that the
fuel line inside the tank that delivers fuel from the pickup in the center
of the tank to the outlet at the right rear had come off at the outlet
fitting. It made the van "run out of gas" when it still had a quarter tank
in it. Most exasperating! Someone probably blew air into the tank under
pressure, thinking to clear the line, and blew it off instead. Imagine their
delight when they figures they had solved the problem (the line was
certainly clear, then), and their dismay when the van repeatedly ran out of
fuel such a long way from the next gas station...
