NW Conversions 36 Gallon Wheel Well Water Tank - Sprinter/Transit

NW Conversions 36 Gallon Wheel Well Water Tank

Maximize wheel well space and free up your garage for gear.

The NW Conversions 36 Gallon Wheel Well Water Tank is designed to utilize the wasted space directly above and around your van’s wheel well. It fits tight to the wheel well, allowing you to reclaim valuable garage space for bikes, storage bins, tools, and other gear.

With a 48” long, low-profile design (16” deep × 16” tall), this tank centers cleanly over the wheel well while keeping your water system fully inside the van — ideal for cold-weather travel where exterior tanks aren’t an option.

Vehicle Fitment

  • Transit wheel wells are slightly smaller than Sprinter, providing additional room for insulation

The tank is not designed to be pressurized and must be properly vented in your system.
