Rob,

You will need a boost referenced pump. You need to have fuel pressure rise [from your base fp setting] 1 lb for each lb of boost.

The box and a carb hat function the same way. They both pressurize the carb. The hat also pressurized the bowls through the vent tubes. The box just makes fuel leakage from the throttle shafts a non-issue.


I do not believe that the black pump is capable of supplying enough fuel. If you run, say 8 psi boost, and a 7 psi, you'll need a pump that'll give you enough fuel flow at 15 psi fuel pressure. The pump will probably go 15 psi, but it will not flow well at that pressure.

Most experts will say that a high pressure pump setup with a return style regulator is the best setup.

Nice truck, btw.
