On our truck there was switch under the dash and it was hooked up. There is slots in the dash for the switch but ours was zip tied up to wiring harness under dash panel right hand side. Also there is a gas valve inline from tank to fuel rail that needs to be turned on. Hope this helps
1st, on a truck this old, it is very possible that while it may have had the "dual fuel" option, it is possible that one type of fuel may no longer work if the previous users never used that type of fuel. it is also very possible that parts are missing and the gasoline has gone bad from age.
look under the hood on the side near the fuel inlet port of gasoline,
Hi thank you most helpful i will check this today not holding my breath for any instruction decal though as it has had a hard life bless her and thank you for the paint colour will see if our local guys can do this.
In the engine area there is usually a key or toggle switch with a instruction decal to change fuel types. The L.P. system should have a inline carburetor with a cable connected to it that will need to be pulled or pushed.The original cables have instructions on the ****. The gasoline tank will have a manual shut off that may need turned on. We get our paint mixed by a local paint store but I think it is called Jewel Green.
This switch your looking for controls two shut off Solenoids....one for the LPG and one for the Gas
Thanks Kevin nothing on the dash so i will trace the pipes and see where they go to.
Regards

To change fuel over there should be a switch either on the dash or engine compartment,maybe near LP vaporizor,turn to LP/gas...as for the paint,sorry can't help with that one.
