INSTALLATION:
1.
Install the fuel tank sender unit using a new O-ring seal.
NOTE: Care should be taken not to fold over or twist the strainer when installing the sending unit, as this will restrict the fuel flow. Also, make
sure that the strainer does not block the full travel of the float arm.
2.
Install the insulator pads on top of the tank to reduce rattle and other annoying noises. Peel off the release paper and apply the insulators to the
tank. Apply tape to the front insulator, using one 330 mm or two 130 mm pieces of tape.
3.
Position the fuel tank under the vehicle and partially raise and support the tank.
4.
Connect the vapor purge hose to the vapor tubing.
