hey I have just rebuilt my whole propane system, from the shut off to the carb. The first things you should do is replace the propane filter located in the shut off. If you have an impco system this is easy. Do you have a vaccum shut off or a electric? next I was told it was not needed, but my truck had been sitting for about 3 years so I rebuild the convertor, impco model E easy to do when you Follow the instructions. propane is relitivly simple to work on.
Filter cost $5
Impco Model E rebuild Kit $108.95
