Ranger Mods

Having come across this forum I believe it can help me to move into the 21st century. Previous vehicle an 80 series Landcruiser which had none of the bells and whistles the Ranger has. As it is my tow tug I am particularly keen to install a 140l fuel tank and keep all the functions of the fuel measurement computer.
By for now and I look forward to reading the many informative posts.
