There may be something in the tank that when you go uphill it moves to cover the fuel line. Leon R  Cmo

Low fuel level in the tank.  Fill it right up and see how it works.

I agree. One of our 6080's would surge a bit on corners. Ended up finding a bit of debris in the tank.

Try a new fuel tank fill cap. The vent might be plugged causing a vacuum in the tank.

Put a clear plastic hose from filter to inj pump . Sounds like sucking air. When going up hill it takes more fuel, so it sucks more air. With the clear tube you can see the air.   MACK

Debris in the fuel tank moves to cover the tank outlet when you go up hill?  After 40 years, I would think those tanks could use a good cleaning.
