Anyone who may know...my lockout valve and the "fuel in" hose feezes up. This results in loss of drive in the vehicle - it will creep forward at an idle but as soon as you touch the accelerator, it will sputter and stall. I looked into this with some local propane mechanics and was told to replace the lockout valve itself. I have done this. The truck seemed to be working fine for about a week and then the same thing happened to me today coming home from work.
Any time that this has happened to me I have had to simply wait a few minutes then try again and everything is good again - until the next time I'm right in the middle of Edmonton and it goes again.
Another guy said it may be the service valve or the hose itself. How can you tell if it is the service valve, or can you for that matter without some sort of special equipment?
Look forward to any feedback.
