A vehicle-specific 62L underfloor water tank designed for Fiat Ducato, Peugeot Boxer and Citroën Relay models from 2006 onwards. Its low-profile 19.5 cm height allows valuable water storage to be positioned underneath the vehicle without taking up interior living or storage space.
 
Manufactured from durable, rotationally moulded MDPE and supplied with a dedicated stainless-steel mounting kit for installation beneath compatible vehicles.
 
Suitable for use as either a fresh water or wastewater tank.

VEHICLE COMPATIBILITY
Designed specifically for:

Peugeot Boxer – from 2006 onwards
Citroën Relay / Jumper – from 2006 onwards
LWB (L3) and XLWB (L4) models
Compatible with Euro 6 AdBlue versions
 
Not suitable for vehicles fitted with rear air suspension.
 
The vehicle-specific shape is designed around the Ducato/Boxer/Relay chassis, making this a much more straightforward underfloor solution than adapting a universal rectangular tank.
 
MOUNTING KIT INCLUDED
The tank is supplied with the dedicated hardware required for secure underfloor installation, including:
4 × stainless-steel mounting brackets
20 × Tek screws with sealing washers
8 × M8 screws
 
This eliminates the need to separately source or fabricate a mounting system for the tank.
 
CONNECTIONS & VENTING
The tank incorporates both 1/2" BSP and 1 1/4" BSP brass threaded connections, providing suitable connection points for integration into a campervan water system.
 
It also includes 2 × pre-installed 1/2" vents.
 
The 12 cm flat, non-vented inspection lid provides access to the inside of the tank for inspection and cleaning.
 
FRESH OR WASTEWATER USE
The food-safe MDPE construction means the tank can be used for fresh drinking water, while its underfloor location and durable construction also make it suitable as a grey/wastewater tank.
 
This gives builders flexibility to use the same vehicle-specific tank design on either side of the water system.
 
TWIN TANK OPTION
For installations requiring significantly greater capacity, this 62L tank can be combined with the matching 92L underfloor tank to create a 154L twin-tank system.
 
The combined installation requires the dedicated twin mounting kit, which is different from the standard mounting kit supplied with this individual tank.
 
INSTALLATION
The tank is designed for permanent installation underneath the vehicle using the supplied stainless-steel mounting brackets and fixings.
 
A full 62L tank contains approximately 62 kg of water, in addition to the tank's own 8.5 kg weight. All mounting points and surrounding vehicle structure must therefore be capable of securely restraining the tank when full and while the vehicle is moving.
 
Always confirm vehicle compatibility and available underfloor clearance before installation.
