If you are DIY inclined, you may be able to fit your long range tank yourself, as we have for our 80 series Landcruiser. It is generally suggested however, that a replacement tank is fitted by the distributor. Some aspects of the installation require careful consideration such as extending the fuel sender and lifting the tank into position. In some vehicles, the long range tank fists into the spare wheel bay (eg. 80 series Landcruiser) and is a far more practical use of the space. As a spare wheel bay this space is pretty useless for offroad terrain as the wheel becomes the lowest point and can drag in the sand, especially if your tyres are deflated. Get it out from under there!
Once you've installed a long fuel tank you may also see the need for suspension
changes to compensate for the added load of fuel.
