💧🚐 This 75 litre underfloor water tank has been purpose-designed for the L2, L3, and L4 models of the Fiat Ducato, Citroën Relay and Peugeot Boxer (>2006–2026). Suitable for use as a waste water tank, it is ideal for campervan and motorhome conversions.
Manufactured from durable, corrosion-resistant polyethylene, the tank features a matt black finish for a discreet and long-lasting underfloor installation. Its hygienic, algae-resistant construction ensures reliability for long-term van builds.
A large threaded access hatch is fitted on the top of the tank, allowing the installation of pumps, internal accessories or sensors, and providing access for periodic cleaning.
What’s Included-
1 × 75L Water Tank (L: 1000mm, W: 300mm, D: 225mm)
1 × 1/2" Elbow for attaching the breather
1 × 3/4" Elbow for connecting the waste pipe
1 × 1m long 1/2" Breather Pipe
1 × 2m long 3/4" Convoluted Black Hose

Locating Instructions
This tank installs widthways (driver side to passenger side) in the cavity between the two chassis members, located directly behind the exhaust silencer.
The service hatch must face upward, with the corner cut-out positioned around the handbrake cable.
Due to the handbrake cable location:
L2/L3 models can fit one 75L tank underneath
XLWB / L4 models can fit two tanks, provided no aftermarket modifications occupy the mounting space
⚠️ Important Information
Water level senders are also available, including models compatible with Victron & SRNE systems (Click Here)
Tank may contain traces of water on arrival—this is normal due to leak testing.
Please ensure the tank is fully cleaned before use.
