Details
Maximize your van’s interior space with this cleverly designed 20-gallon freshwater tank that fits snugly around the Sprinter van’s wheel well. Whether you place it on the driver or passenger side, it optimizes unused space while providing easy installation and access:
Passenger-side orientation: Sits mostly behind the wheel well and aligns flush to the front.
Driver-side orientation: Sits mostly in front of the wheel well and aligns flush to the back.
Crafted specifically for Sprinter vans (including the Sprinter 2500 and T1N variants) and compatible with Transit single rear-wheel models, this tank can also adapt to other van makes and models.
Specifications:
Dimensions: 44.5″ long × 12.5″ deep × 16″ tall
Material: BPA-free, food-grade polyethylene plastic—safe for drinking water
Ports:
Two 1.5″ NPT ports (inclusive of drilling required)
Two ½″ NPT ports on the rectangular end
One ½″ port on the bottom of the open end
One 1.5″ NPT port on top for fills or level sensors
Design note: Non-pressurized—venting required

Vehicle Fit & Installation Notes
Transit vans have slightly smaller wheel wells than Sprinters, leaving more room for insulation.

Promaster vans require the tank to be elevated by approximately 3.5″ to accommodate larger wheel wells.
