20 Gallon Wheel Well Water Tank (Left)

Smart Fit. Clean Layout. Built for Sprinter Van Water Storage.

The 20 Gallon Wheel Well Water Tank (SP-L-20) is engineered to maximize otherwise wasted space around the wheel well, providing efficient water storage without sacrificing interior layout options. Designed for Sprinter builds but compatible with additional van platforms, this tank delivers a balanced footprint with flexible left-side installation.

Fitment

Designed For:

• Mercedes Sprinter 2500 (all lengths)

• Sprinter T1N

• Promaster wheel wells are larger; tank must be elevated 3.5" for proper clearance.

Placement Options
