Make sure you rotate the locking ring until the rib on the OEM locking ring is fully seated into the indentation on the S&B receiving ring.

On the OEM fuel tank, use a 19 metric socket to 2 strap bolts which hold the stock fuel tank into the skid plate.

Place the S&B Tank in the OEM skid plate, reassemble the straps using a 19mm socket.

Position the S&B Tank on a jack and raise the tank until you are able to reconnect sending unit connections. Ensure the vent lines are positioned through the frame properly.

Reconnect the electrical connector on the sending unit. Slide the red locking tab back into the locked position.

Reconnect the fuel line connectors by pushing down until they are fully seated. Push the fuel connector locking tabs back in once the connectors are fully seated.

With a 15 metric socket, reinstall the 4 bolts that hold the fuel tank skid plate assembly to the truck frame. Hand torque the bolts to make sure all 4 bolts are tight.

Slide the vent hoses onto your S&B Tank and use a flathead screwdriver to tighten hose clamps.
