If there's any crud in the fuel pump you run the chance of screwing up your carb rebuild. Do you have a filter between the pump and the carb? At a minimum, if you're going to do that, I'd disconnect the fuel line at the carb, crank the engine and shoot the gas into a can for a few seconds. Be sure there is NO SPARK by REMOVING (not just disconnecting) the coil wire.

WARNING: If your skill level is low in this area, don't do this. If you spill gas or otherwise ignite it this is a great opportunity to burn your truck to the ground. (Ask me how I know.)
