There is two major problems and is due to the systems age.
Current automotive LPG tanks must be fitted with a AFL and a gas lockoff on the tank itself.
A AFL is a automatic fill limiter (shuts off the gas at 80% fill and saves the use of the ullage valve when filling)
On all systems now a small electric fuel shut off valve is fitted on the tank in case the gas line from the tank to the motor is damaged.
The power for the valve is supplied from a vacuum switch or black box which also supplies power to another gas lockoff on the gas convertor.
Your tank may or may not have the AFL valve.
It will not have the extra lock off valve and therefore would need to be up graded.
If this is all worthwhile against the price of a new tank I do not know.
