NW Conversions 20 Gallon Driver Side Transit Undercarriage Water Tank (TR-UC-20)
Maximize your Transit’s water capacity with a driver-side undercarriage tank that uses your existing fuel strap bolt locations.
The TR-UC-20 mounts under the driver side of your Ford Transit, next to the OEM fuel tank, using existing fuel strap mounting points to minimise drilling. Three stainless laser-cut straps and all hardware are included. Suitable for fresh or grey water, and sized to give serious water capacity without compromising your interior layout.
Built from food-grade, BPA-free polyethylene and certified to IAPMO TS-4 / RVIA standards. Made in the USA by NW Conversions.
⚠️ May NOT fit Transit vans with a rear passenger heater or AC unit due to heater lines in the mounting bay. Consider the TR-UC-16 if your van has this option.
