If the tank is dry inside ie no fuel left in it and the floor pan is the same on both trucks it should be an easy swap.

The tank its self is not a problem however diesel and petrol have a different fuel system. The diesel has a fuel return line to the tank from the engine and the diesel fuel system will not tolerate air in the system. There are a couple of ways of fitting a reserve tank but if you are doing it yourself the easy way would be to link up your main tank with a 12v transfer pump and a switch on the dash. There is a small problem with this setup if you forget to switch off you may overflow your main tank. Hope this is some help.

A follow on from Nav 80, put a return line from the main back to the Aux and you can never overfill, other wise follow the above instructions.

Ditto, used an old petrol tank as my aux, a fuel transfer pump also switches a relay to read the level in the aux tank. Can't overfill the main because it just overflows back to the aux (reserve) tank.
Works a treat and cost only a few dollars- virtually all the parts from wreckers.
