Go to Tanks website and pick out the sender and fuel pump you want, then put those part numbers in on Summits website. GPA-2 fuel pump if under 450 HP, GPA-4 for up to 630 HP and TAN-ORG fuel level sender for mopar. Holley also sells this tank/pump/sender bundle under PN#19-183

Spectra used to make an EFI conversion tank that the pump module went in the side on the tank like the stock sending unit for the 66-67 cars but I don't see it listed. Have used this tank for a few lower HP builds and it works good other then the fuel level ohms are not right for Mopar.
