What You'll Learn
Long-range fuel tanks for Jeep Wranglers
There are several options for extended-range fuel tanks for Jeep Wranglers. These options vary depending on the Wrangler model and year.
For the Jeep Wrangler JL 4-door models from 2018 onwards with a 3.6L V6 gas engine, there is a 17-gallon long-range auxiliary fuel tank available. This tank fits on the left side of the driveshaft and uses a transfer pump to fill the main tank when a switch is activated. With this additional tank, the total fuel capacity is increased to 38.5 gallons.
For the Jeep Wrangler JK 4-door models from 2007 to 2011 with a 3.8L V6 gas engine, there is also a 17-gallon auxiliary tank option. Similar to the previous option, this tank fits on the left side of the driveshaft and uses a transfer pump to fill the main tank.
Another option for increasing fuel capacity is to consider a 10-gallon LongRanger tank. This tank comes with its own fuel gauge and a transfer pump, allowing you to refill your main tank while driving. However, it is unclear if this tank fits with the eTorque battery or certain exhaust systems.
Additionally, GenRight offers a range of fuel tanks for Jeep Wranglers. They have a 25-gallon muffler delete tank specifically for 4-door models, although it is unclear if it will work for 2-door models. GenRight also offers a 40-gallon gas tank and a 36-gallon gas tank with a skid plate for elite suspension.
It is important to note that some extended-range fuel tanks may require modifications to the vehicle, such as redesigning the rear bumper or tyre carrier system. Additionally, some tanks may not be compliant with the regulations of certain states or countries, so it is essential to check before purchasing.

Rear-mounted tanks vs. tanks mounted opposite the main tank
There are a variety of options available for extended-range fuel tanks for Jeep Wranglers. These options include both rear-mounted tanks and tanks mounted opposite the main tank.
Rear-mounted tanks are typically aftermarket aluminium racing fuel tanks that are bolted down inside the back of the vehicle. These tanks range in price from $100 to $500, but they may require significant modifications to the vehicle, such as cutting through sheet metal for the filler neck or redesigning the rear bumper and tire carrier system. Some users have expressed concerns about the level of effort and cost required for installing rear-mounted tanks, especially when compared to the convenience of using jerry cans for refuelling.
On the other hand, tanks mounted opposite the main tank, such as those designed by Long Range America (LRA), offer an alternative option. These tanks are designed to be mounted on the left side of the driveshaft, opposite the OE gas tank, providing maximum clearance. The LRA tanks have a capacity of 17 gallons and use a transfer pump to fill the main tank when a switch is activated. This option may be more appealing to those who want to avoid the hassle and cost of modifying their vehicle to accommodate a rear-mounted tank.
It is worth noting that the LRA tanks are constructed from 2mm aluminized steel and do not require an additional guard for protection. Additionally, these tanks are designed with provisions for the exhaust system, addressing a common concern with rear-mounted tanks. However, it is recommended that the installation of LRA tanks be undertaken by an experienced and well-equipped workshop to ensure proper fitment.
Both rear-mounted and opposite-mounted extended-range fuel tanks offer increased fuel capacity and the convenience of avoiding frequent refuelling stops. The decision between the two options ultimately depends on factors such as vehicle configuration, desired level of modification, and personal preferences.

Aluminium aftermarket fuel tanks
There are several aftermarket extended fuel tank options available for the Jeep Wrangler. These options are designed to increase the fuel capacity and range of the vehicle, providing added convenience and security during long-distance travel.
One popular choice is the Long Range Automotive (LRA) auxiliary fuel tank, which offers a capacity of 17 gallons. This tank is designed to fit Jeep Wrangler JL 4-door models from 2018 onwards with a 3.6L V6 gas engine. It is installed on the left side of the driveshaft and uses a transfer pump to fill the main tank when activated by a switch. The LRA tank provides a total fuel capacity of 38.5 gallons when combined with the original tank, enhancing the vehicle's range.
Another option is the GenRight Off Road aluminium fuel tank, which is hand TIG welded and pressure-tested in the USA. These tanks are CARB-compliant and utilise the factory fuel pump or fuel module, ensuring compatibility and ease of installation. GenRight offers a range of options, including auxiliary and replacement fuel tanks made from 1/8" thick aluminium alloy.
Some Wrangler owners have also considered aluminium racing fuel tanks as an aftermarket solution. These tanks are bolted down inside the rear of the vehicle and offer various form factors and capacities. The price range for these tanks is typically between $100 and $500, making them a more affordable option.
It is important to note that when installing aftermarket fuel tanks, considerations such as exhaust configuration, bumper design, and tyre carrier systems may come into play. Additionally, fuel gauge accuracy may differ after installing a replacement tank, with low fuel warning lights generally operating at the same level as the original tank but with a greater reserve capacity.
