Have just completed fitting the extra fuel tank on my Peugeot J5 chassis. For some reason the fitting of long range fuel tanks is not as popular as it is in Germany. I think the reasoning behind this is that most Germans transit Luxembourg when traveling south,so they take advantage of cheaper fuel there. Anyway have just fitted a 70 ltr fuel tank from an LDV to the Peugeot,pumped through to the main tank via a 12 volt fuel pump,switchable from the dash. The LDV tanks are perfect for European campers as they are long and narrow so can be bolted straight to the chassis and with a little alteration to the filler pipe and a piece of ex inter-cooler hose brought up to the sidewall and a nice flush fitting filler cap on the outside. Hopefully this will give me enough range to most meets and trips in the UK without having to buy fuel out. Also with luck can make Spain with only one fill-up on route. I fitted a similar setup to my VW but am realy pleased with the outcome of this one as its all done from the cab whilst on the move. No getting out and switching taps on and off.
