There are two considerations when buying
a propane tank.
The first is do you want to supply propane gas or propane liquid to your appliance? Stoves want gas and larger engines (like forklifts) want liquid.
Second, will the tank be mounted vertically or horizontal. The reason this is important is the overpressure vent. If the tank is mounted incorrectly, and in a fire it has to vent to avoid an explosion, it can vent liquid instead of gas as it is supposed to.
I learned this while working in the Lehr outboard
booth at the Miami boat show
. I mentioned that I was going to mount my regular tank upside down to feed liquid to the engine
. There was a guy from the company that makes the Lehr fiberglass
tanks there. He pointed out the danger
of this plan. Now I plan to get a forklift tank that is designed to provide liquid propane. Only the Lehr 15 wants to be fed liquid, the smaller engines run fine on propane gas.
Trident Rubber Co. sells a wide selection of propane tanks for use on boats. I believe all the tanks they sell supply propane gas not liquid.
