Yeah I have a nice anchor and Chain just in case.
Cool, I look forward to your review of the trifuel kit.
They didn’t give specifics on the feed hose side. But from my experience 390cc at ~12hp with a 10,000Btu per hp rule of thumb is 120,000btu
As long as the line can support 120,000btu then 1/2 hose is plenty for up to 6’ for natural gas and 12’+ on propane. For over 6’ on natural gas 3/4” hose. Honestly For propane 3/8” is sufficient at 6’.
I would definitely use full bore gas valves instead of standard valves. And on natural gas, I always try to home run as close to the meter before any branch tees.
