I've got a LPG ONAN powered welder generator and have yet to have it run out of fuel, I've run it welding for 8+ hours straight on a forklift sized tank (32lbs?) and still had plenty left at the end of the day. I'm thinking a single cyl. engine should go 14-14 hours on a grill tank with no problem. I guess I need to find out what it needs for a regulator and give it a shot!
