New upgrade installed

1.Remove the small tin cover on the rear of the cam plate cover before reinstalling the cover on the pump. This is the smoke screw adjustment. This does not affect horsepower but how quickly the pump adds fuel. If the truck accelerates slowly, turning the screw in “clockwise”, one turn will speed things greatly. If you get too much burst throttle smoke then turn the screw out “counterclockwise” to reduce smoke. A 3 mm. Allen and a 10 mm. box wrench are needed for adjustment.

2.Reinstall the cam plate cover making sure to reinstall the original gasket under the cover and tighten all hoses and brackets.
