Installation

The first step in installation is to carefully assess the vehicle and pinpoint the ideal placement for the tank. This involves considering the vehicle's unique setup, including the existing fuel tank and any other modifications. The goal is to position the new tank seamlessly so that it integrates with the vehicle's existing setup without affecting performance or handling.

For example, the ARB Frontier long-range tank is designed to replace the factory fuel tank. To install this type of tank, the original factory tank is removed, and the new tank is fitted using the original equipment, including fuel pumps and pickup senders. The new tank connects to the vehicle's original fill point, allowing for fast and easy fuel delivery. The fuel sender is then dropped into the new tank's unique mounting flange, and it operates similarly to the original equipment (OE) tank.

The cost of installation can vary depending on the vehicle and the type of tank. In addition to the cost of the tank itself, there may be additional charges for fitting and any necessary modifications. It is recommended to consult with a professional installer to get an accurate quote for the specific vehicle and tank combination.

Some long-range fuel tanks may also require additional accessories or modifications to the vehicle. For example, the weight savings offered by some tanks can allow for the addition of other accessories. It is important to consider the overall weight and balance of the vehicle when installing a long-range fuel tank and making any necessary adjustments.
