This is a GN1Performance "Aluminum Gas Tank" for a 1986 or 1987 Buick Grand National, T Type, Turbo T, or GNX 3.8 liter turbo V6. Saves 5 lbs over the stock tank and eliminates the need to cut your trunk floor to install a fuel cell.  Not sold with any hardware and you must come up with your own straps to mount the tank. This all aluminum gas tank features a sump at the rear and a bung for a return line as well.  The tank has baffles inside to decrease fuel sloshing.  Designed for use with an external fuel pump and your stock fuel level sensor.  Can be used with an in tank pump with minor tweaking of the pump return.  You must also adapt a fuel filler tube to the tank.
