All the kits I've gotten from NAPA included a pump and everything else you will need. Save the old air horn gaskets as you may need to double up on them. Also, get a Mic to set the float level with, haha. These carbs are a lot more sensitive to float level than most. The gauge in the kit is just a starting point. Set it, run it and check the plugs, a little float level off either way and they will be white or black. Welcome to the world of Rochchester B's.
