hi aaron, i concurr with tom. the pumps have a return line going back to the tank. so they are self bleeding.if you are having trouble keeping air out of the system you could have a weak pump or cracked injector feed pipes.fill the filters up and make sure the return line is unplugged.you may need extra strong batteries to crank the engine over long enough for the pump to prime.email if you need more help, jim.
