1979 Ford 16 ft Box truck 460 motor looses pressure and cut off when going up a hill. It has a 460 motor...very strong. I set on the side of the road and 10 minutes later it drives fine once the pressure builds up.
It is a 1979 16 foot box truck. It is like it does not get any gas. I changed the fuel pump. The same thing happens.
How about the fuel filter?
Check the fuel filter and the carb floats.
