Letter Re: How Do I Transfer Propane Between Tanks?

You mentioned the liquid propane dual-fuel vehicle, and said “…if you have a large home LP tank”. So, how do I get the gas from the large tank, to the vehicle.” Is there a pump or some sort of device? Thanks, – Brad S.

JWR Replies: There is no need for a pump. Draining liquid propane from a tank, is a self-siphoning process. Talk to your propane delivery man. Tell him that you want to be able to refill your barbeque’s 20-pound tank from you main tank’s liquid withdrawal valve. The adapter fittings are made of brass, and fairly hard to find–but propane company employees know where they can mail order them. For a detailed description of what you’ll need, see this thread, at an RV Owners’ discussion page.
