TBI puts out 12 - 15 PSI. You can easily put a regulator between the supply and return lines to drop it down to carb pressures. Actually a really nice option, esspecially if your carb's fuel bowl is always empty. Turn the truck on, let the pump run for a few moments to fill the fuel bowl, then hit the key. Should fire pretty much immediate. Just hook the fuel pump up with a relay that is controlled by an ignition / crank power source, and the fuel pump will run as long as your truck's key is in the on position. Won't matter if your engine isn't running, as the regulator will return excess fuel back to the tank.

Shouldn't need to worry about baffles in your fuel tanks either, as the carb's fuel bowls will keep the engine running even if the fuel pump sends some air down the line.
