This water tank has been designed for the L2, L3, L4 Fiat Ducato, Citroen Relay and the Peugeot Boxer from 2006 – 2019 and can be used to supply fresh water or as a waste water disposal tank. We’ve paired the tank with the autocraft water tank backfill system, which allows you to quickly and easily fill your water tank using a standard hozelock connection.

These underfloor water tanks are manufactured from durable polyethylene corrosive resistant plastic and are supplied in a matt black finish

There is one large threaded access hatch fitted on the bottom of the tank to allow you to fit any additional items such as a pump etc. and allow periodic cleaning.

This tank does not come with any ancillary fittings and these will need to be ordered separately to suit your particular vehicle. Please see our other listings for the range of fittings available.

Please note that no fitting brackets are supplied with this tank. However, we do stock a universal fitting kit, please see the related items below.

Autocraft water tank backfill system:

We have used this product on our own conversions and have not yet found a vehicle that it is not compatible with. The bracket is a universal fitting which means it can be placed anywhere suitable on your van, and you can avoid cutting a hole in the side of your van. This system can be fitted to new conversions or retrofitted to existing conversions.

As well as being easy to set up and quick to use this system also lets you use your water tank as a jet wash tank, providing your jet wash draws water. The backfill system doubles up as a water outlet so you can empty your tank when needed without installing a separate drain tap.

Assembly Instructions

This tank fits widthways (driver to passenger side) across the van in the void between the two chassis members, directly behind the exhaust box. The service hatch will face upwards with the corner cut out going around the handbrake cable.

Due to the placement of the handbrake cable on this van, this is the only place the tank will fit therefore you will only be able to fit one 75 litre tank underslung unless you have an extra long wheel base (XLWB) vehicle. The XLWB (L4) variation of these vans will allow for x2 of these tanks to be fitted providing there are no aftermarket modifications on your van.

To assemble the backfill system, the 15mm to 1/2″ adapter has a push-fit fitting which simply clicks into the heavy duty hand valve. On the other end of the heavy duty hand valve is a threaded 3/4″ BSP fitting, the aluminium bracket is placed on this end and then the hozelock is screwed on tight (over the thread of the tap) to complete the kit. You can screw the hozelock on to the tap by hand but it needs to be as tight as possible, we recommend using plyers to ensure a secure and perfect seal.

To fit the water tank fittings you will need to drill holes in the desired locations of the tank, place the threaded fitting into the hole (with the seal on the outside of the tank where any seals are supplied) and then affix and tighten the bolt on the thread using the tank’s access hatch to reach the inside.

The breather inlet should be placed as high as possible on the tank. The water feed outlet, for water going into the van, should be placed as close to the bottom of the tank as possible. The water inlet should also be placed close to the bottom of the tank so that it can also be used to drain the tank.

When attaching the pipe to the water tank fittings we recommend putting the pipe into hot water first to increase its flexibility.

In order to fit the tank we recommend using our Universal Water Tank Mounting Strap Kit.
