My dad bought a Holley list 7855 carb to replace his leaky q-jet on the 350 in his truck. I know it's a Mopar carb, double pumper 650 cfm 4bbl w/ spreadbore and the fuel inlet is correct for a Q-jet swap.. Can the line coming out under the inlet be blocked off? I think it's a return line.. This is the identical carb
