The 92-Litre Underslung Water Tank is a vehicle-specific water storage solution designed for Fiat Ducato, Peugeot Boxer, and Citroën Relay long-wheelbase campervan conversions. Mounted beneath the vehicle chassis, the tank provides substantial onboard water capacity while preserving valuable interior storage and living space, making it ideal for motorhomes, campervans, and off-grid touring vehicles.

Manufactured in the United Kingdom from durable rotationally moulded polyethylene, the tank is designed specifically for Fiat Ducato platforms from 2006 onwards, including L2, L3 and L4 variants, and is also compatible with equivalent Peugeot Boxer and Citroën Relay models.

Design Benefits
Maximises Interior Space
By mounting beneath the vehicle, the tank frees up valuable internal storage and living space that would otherwise be occupied by a large water container. This is particularly beneficial for campervan conversions where every centimetre of interior space matters.
Large Water Capacity
With 92 litres of storage, the tank provides sufficient capacity for extended touring and off-grid camping, reducing the need for frequent refilling.
Flexible Installation
The tank can be installed as a fresh water tank, a grey waste water tank, or as part of a twin-tank system when paired with Wydale's 62-litre underslung tank. This flexibility allows builders to tailor the system to their conversion requirements.
Connection Points
The tank includes:
- 1 × ½" BSP female outlet
- 1 × 1¼" BSP female outlet
- 2 × ½" BSP pre-installed vent connections
- 1 × 5" internal inspection lid
These connections allow easy integration with water pumps, fill points, drain systems, vent systems, and water level monitoring equipment.
