Store the fuel

The fuel remains inside the containers, and you can store the remaining volumes in a separate tank. It prevents various losses and other harmful circumstances. 

The budget remains in proper control due to such activities. These storage conditions are like preventive measures before initiating such procedures. 

Remove its cap

There is a cap on the fuel gas filler, and it requires removal. You cannot proceed to the next steps without removing such tools. Use a sharp tool to detach the cap from the fuel compartment.

Insert the tool beneath the cap and pull it outwards. Keep it aside to install it again in the system. 

Discard its brackets and screws

There are mounting brackets that hold the fuel filler neck and its tube.

Adjust the bolt puller and remove these bolts from their original points. Next, remove the screws with the help of a Philips screwdriver. Finally, remove the brackets with wrenches and sockets. 

Remove sheets of the fuel tank

Discard the metal portions from the fuel tank with the help of proper tools. For example, the wrench helps to discard the bolts from these shield components. You can also heat the metal sections and discard them from the attachment points. 

Remove the lower bolts

There is an arrangement of hinges that attaches with bolts. Apply the oil for smooth flow on the tank straps. 

These straps are holding tools with excellent stretching. In addition, they tie the fuel tank with accurate adjustment. 

Use a bolt puller or a wrench and remove the two bolts of the hinge section. Take the help of a friend when the fuel tank loses.

Adjust the fuel tank on a stable surface after its removal. It protects from the sudden falling of the fuel tank on the ground. The avoidance of instructions can cause damages to the fuel tank.

Use a tool to move the clamps

Detach the clamps from the hose of a fuel tank with a screwdriver. Remove all the holding points and add a bolt on the opening. 

It removes all the errors of leakage and preserves the fuel inside the tank. 

Disconnect the electric passage of the system by removing the electric wired.

Observe the connections and remove them accordingly. The spring connections are pulling, and you can disconnect them conveniently.

Detach the fuel and gas tank and adjust them aside.

Hold the bottom side of the filler neck tube and push it outwards. The pressurized fitting of the filler neck is removable in such ways. Detach the hindering clamps during such procedures. 

Twist the filler neck tube when the removal becomes challenging. Remove and discard the O-shaped ring from the fuel filler neck. Detach the rubber hose from the tanks and then lead to the next steps.

Remove the fuel filler neck with its tube from the attachment point.

Make sure you never leave a small piece of metal in such detachments. The presence of remaining parts can make the installation tricky. 


Apply greasing oil on the O rings and other clamps. Then, adjust it in the groovy section of these fuel tanks. 

The greasing offers smooth flow and stability of the equipment. You can attach everything without any problem.

Adjust new device

Adjust the new filler neck tube in a precise place. Adjust the brackets for accurate adjustments and never allow their sliding. 

Ask a friend to hold the fuel tank and then adjust the top side brackets of the neck. Next, adjust the screws in the openings and tight them with proper tools. This also helps to fix the loose fuel door.

Reconnect the removed parts

Reconnect the removed straps around the fuel tank. Adjust the electric wire system, and put back all the bolts. 

Replace the shielding material and fix it with wrenches. 

Fill the fuel tank and then connect the batteries. Turn the connection on and then check the performance of the device.
