Been there, tried that- - - - - -didn't work! I was attempting to meter liquid Propane through an aircraft-type pressure carburetor. You MIGHT get away with gasoline, if you supply enough fuel pressure (at least 25 PSI). The altitude-compensating function leans the carb out at high altitude to compensate for the less-dense air up there. I don't know if the carb would be sensitive enough to adjust for sea level VS. Denver @ 5,000 feet, but it might work on Sonora Pass at 10,600 feet. Good luck if you try it. The carb would need to be calibrated for an engine approximately the same CID as the truck.
