Are you planning to use an onboard propane/butane canister or straight from the can it comes in?
If you use an offboard bottle with an on/off tap and a quick release connector then you don't need the solenoid on the gas line (but keep the one on the fuel line). This also has the added benefit that you're not flying around with a pressurised gas source on your model.
