Sprinter Long Range Fuel Tank (45 Gal) AWD 2023+

Regular price $1,549.00

Unit price per 



Designed to solve one of the biggest pain points of any Sprinter, the small fuel tank/lack of range. This new 45gal tank is specifically designed to fit the new AWD Sprinter model 2023 on.

One of the biggest pain points with a built-out Sprinter is the undersized fuel tank. The whole point of an adventure van is to get off the beaten path. The problem is that every adventure seems to include constant fuel stops. Additionally, vans need more than 1/3 of a tank diesel for the heating system to run properly.

This new Sprinter high capacity 45 gal replacement tank upgrades the stock 26gal and almost doubles the capacity! Now the only limiting factor on your journeys might be your bladder :)

This tank is manufactured just like the factory tank and bolts right into the same location (inside the frame rails). Also includes the aux port for your heating system that comes on the factory tank. Manufactured from a higher grade of polyethylene (the material in the factory tank) means it's even more rugged than factory!

    Professional installation suggested. Installation is additional.

    Some builds can have additional tanks like gray water etc and these might make installation of the tank more difficult or impossible. Please be sure to check under your van before ordering. Returns for vans due to aftermarket equipment will be the responsibility of the customer.

    Canceled Orders

    We want all customers to be happy with their purchases but in the event of a canceled order, we cannot recoup the fees charged to us by the credit card companies. When an order is placed, the credit card company takes a percentage of the sale, typically 5%-6% This is money that DOES NOT go to us and we do not get this charge given back to us when we refund an order. Therefore, if someone buys a suspension and then cancels, we pay the credit card company several hundreds of dollars that we cannot get back. Although you may not have noticed, it is industry standard for larger dollar items to have a "restocking fee" of 15% or more. We do our best to charge exactly what we get charged by the credit card company when you cancel an order. In the event of a canceled order, the 5%-6% that the credit card company charges us cannot be refunded. Please make note of this before you order. 

    • All canceled orders over $1000 paid with a "Credit Card" will have a 5% credit card processing fee that cannot be returned.

    • All canceled orders over $1000 paid with a "Shop Pay Installments" will have a 6% credit card processing fee that cannot be returned.
