Drive further. Adventure longer. Sprinter Fuel Tanks

Picture this… You’ve purchased a new Sprinter van. You finished the interior build. Loaded up on accessories. You improved the harsh (and sometimes unstable) ride, plus gained a couple inches of ground clearance with our RIP-Kit. And lastly, you finish it off with a set of aftermarket alloy wheels & all-terrain tires. Your adventuremobiles’ got everything it needs, except you STILL can’t go everywhere you want. Why?… Because of the limited fuel range.

Sure, with about 340 miles of range from the factory 24-gallon fuel tank (averaging 15 MPG) you may think a gas station is never completely out of reach. But when you’re mapping out a trip, Google Maps only shows the most direct route. What’s the fun in traveling like that? You can’t possibly plan for every rest stop, what’s-over-there moment & scenic detour. Not to mention what are you going to do when you arrive at your destination? Stop, park, and don’t run the rig until you pack up and head home?….Uhh..No way!

Put your endurance to the test. Imagine being able to drive from San Diego, California to Moab, Utah WITHOUT making A SINGLE STOP. Not only will you and your co-pilot not need to stop on the way. But also be able to run your rig for heat or to power up equipment. Explore more of the area around your camp ground without concern for how you’ll get back out.

We offer several (auxiliary & replacement) diesel fuel tank solutions for the Mercedes-Benz Sprinter. Starting with a 14 gallon auxiliary unit all the way through a 48 gallon replacement tank. Depending on your van’s configuration you could potentially add an additional 62 gallons of fuel capacity (via driver side, passenger side & rear auxiliary tanks) to the stock tank’s 24 to give you almost 1300 miles of range.

Adding an auxiliary fuel tank to your Sprinter makes sense from a practical & logistical standpoint as well. With the increase in fuel capacity from the large tanks you can now really take advantage of filling up at the cheap gas station (which is usually quite a ways from the campsite). It also allows you to travel through areas (such as Central Mexico) where poor fuel quality may be a concern.

    This is wonderful news. NOW if you could just do the same for the FORD TRANSIT! I have a 2016 Ford Transit 350 with the popular ecoboost twin turbo gas engine and I am sad to say that my tank is only 26 gallons and I get 11.5 mpg or a total range of <300 miles! PLEASE help us with a similar solution to what you have done with the Sprinter.

  2. Looking forward to seeing your 48-gallon replacement tank as none of your auxiliary tanks works for my van due to undervan water tanks, heater and batteries in all of the places of your aux tanks but the factory replacement should work. Does it extend further to the back of the van and/or also to the middle of the van but not to the outside of the frame rails?

    1. Elikem Moten

      KC, fitment as you know is dependent on your Sprinter’s layout. The replacement tank extends over into the driver’s side cavity (outside of the frame rail) so it will not work if there are tanks or batteries mounted on the driver’s side.

    Had a 12 gallon auxiliary (our grey h2o tank made the 14 gallon tank too long) installed 3 weeks ago and what piece of mind an extra 160 miles makes on our 3500 4×4 Sprinter! Wish we’d had it prior to our 2 months in Baja mid winter. Get the marine pump and skip the 2nd filler.

    The SD Agile gang are top notch!

  4. Will the 48 replacement tank work on the Revel?, pricing?, ETA?

    1. Elikem -

      Moises, unfortunately, the water tank, batteries & heater mounted underneath the Revel prohibit the use of the 48-gallon replacement fuel tank. However, moving the spare tire to the rear door/bumper will allow you to add our 28-gallon rear auxiliary tank.

      Pricing for the ACBG replacement fuel tanks starts at $2650 – ETA TBD
      Pricing for the Agile 28-gallon auxiliary tank starts at $1995 – AVAILABLE NOW!

    I’m looking at a preowned 3500 Sprinter with passenger side tank. Capacity based on measurements approx 15 gals. Trying to learn how it works, filters, pumps, who made it. Fill is a cap on p/side. Inside there is gauge with switch. Mfg logo looks loke AMA over star. Can send pictures if needed.

    1. Elikem -

      Ron, please email with details & photos. We’ll get back to you as soon as possible.


    I have a 3500 sprinter motorhome, I know water tanks and batteries may be an issue, what is available to upsize the fuel tank?

    1. Elikem -

      Most motorhomes in our experience have tanks and batteries mounted on the sides of the vehicle eliminating the possibility of using a replacement or side-mounted auxiliary tank. On most 3500 motorhomes we’ve been installing our rear-mounted 28-gallon fuel tank. This should work for you as long there’s no rear-mounted generator. Email us some photos/specifics on your build and we’ll see what we can do for you.

    Would be interested in information on expanding range on my 2016 3500 Sprinter Roadtrek 240

    1. Elikem -

      Gregory, we offer several fuel tank solutions for Sprinter including 14, 20, 28-gallon auxiliary tanks as well as 48 & 58-gallon replacement tanks. To see which solution(s) are compatible with your Sprinter we’ll need to see the undercarriage of your rig. The arrangement of water tanks, generators, batteries, etc. underneath will dictate which options are available to you. Send some pictures to and we’ll get back to you with a quote.
