thats a long draw on the pump , do the bottom drop outlet bungs , you will have to put a valve there as well . or it will drain the tank all the time you work on it . your tank can be welded on if you defuem it , i run a hose from a running cars exhaust into any tank i'm welding on , co2 don't burn . no boom ! and i've still got all my fingers and all my body parts . some will fill it full of water as well . your call , hope you sort this out , was setting my 64 up for the motor trans transfer . just a 69 383 hp rr motor w/ rpm int afb headers w/typewriter auto 63 nyr .
