New Mounting Screws and gasket available separately.
*19-170 kit is a thicker gasket and longer screws for use on the GM A Body (Chevelle, GTO, etc....) fuel tanks since they are shallower at the point where the fuel pump is mounted.
*19-169 kit for all other EFI fuel tanks
Connect your in-tank wire harness to the fuel pump, making sure that the connections are secure. Route the wires through the pass through fitting being sure to leave a little slack to prevent strain or chaffing, Use a 9mm wrench to tighten the upper jam nut on the wire pass through in 1/4 turn increments until the wire no longer moves up and down. BE CAREFULL NOT TO OVERTIGHTEN DOING SO COULD BREAK THE FITTING OR CAUSE A LEAK.
