Only 66mm (2.6") wide. 335 (13") deep and 335 (13") tall. Capacity: 5 litres (5-quarts). Tank adaptor and level sensor are not included (for illustration purpose only) but are included in the HFS3 and HFS4 kits.

Thanks to the internal baffle, it utilises the full capacity more effective compared to a non-baffled tank.
