Before unbolting the straps that secure the fuel tank in place, take away the maximum amount fuel as potential from the tank. this can lighten the tank significantly and build it abundant easier to handle, lower and raise back to place. Some gas tanks have a drain plug within the bottom, however most don't thus might} ought to use a hand siphon pump to empty the tank (do NOT use an electrical drill powered pump because the sparks may ignite the fuel!).

Disconnect the filler neck from the fuel tank by loosening or removing the clamp that holds the hose on the tank.
Remove either the front 2 bolts or the rear 2 bolts that secure the fuel tank straps to the vehicle. Then gently lower one finish of the tank. this can enable you to achieve the wiring connections, fuel line and vent hoses on prime of the tank.
