This fuel tank fitting from Aeroflow Performance allows the user to easily alter a stock tank to have a return fuel line installed. This is great when upgrading to a larger in-line electric fuel pump that requires a return to be installed into the fuel tank. The installation is easy as this acts like a riv-nut insert. Simply drill a hole into the tank, install the riv-nut insert into the tank, and then screw in the supplied bolt into the riv-nut, then lock it into place. A -8ORB to -6AN Male fitting is included to allow the user to plumb up the return fitting.
