SECOND TANK "SHOE HORNED" IN THE BOOT. I think this picture speaks for itself. I was extremely lucky on ebay to get a tank that fitted like this one did. It holds an impressive 10 gallons.
It is now swathed in foil backed loft insulation which has proved to be brilliant in heat conservation. No small thing as this cuts down, if not eliminates "heating up time" when the vehicle is started up on normal diesel. The fuel reaches temperatures of 70 degrees + on a decent journey and is still around 50 degrees 12 hours later!
