Refillable 16 oz. Propane Cylinder

The US BBQ propane tanks have a pressure relief valve in the valve assembly at the top of the tank. In an overpressure situation (think fire) the valve opens limiting the pressure in the tank. If the tank is upright, propane gas comes out, the liquid in the tank boils, cooling the tank. If the tank is inverted, liquid propane comes out at a much higher pound per hour rate than gas (it's denser), little of the propane in the tank boils, and the tank is not cooled. So, in a fire with an inverted cylinder, a lot of propane comes out of the relief valve, the tank is not cooled, and things go really bad really fast.

I have a refillable 1 lb on my lpg water heater. It's in my port hull and there are no ignition sources in that hull. Mine has a valve also and made by worthington.

Has anyone seen the refillable tanks in Canada ? I phoned around to all places I could think of but have had no luck so far.

Look up "Flame King refillable propane" on eBay. While most say shipping in the US, maybe you could email them and get one sent there.

A sad ending to this promising tank system:

Notice of Emergency Recall on Refillable 1-LB Propane Cylinder

The tanks have been recalled.

Late breaking news: Apparently only certain serial numbers have been recalled so the overall concept seems to still be ok.

I use the 7.5 gallon fiberglass horizontal tanks to fuel my Lehr 15. I have custom built deck holders to hold a pair of them under the port float of my 10.5 foot fiberglass RIB. These tanks were designed for lift trucks and are very heavy duty. Plus you can see the fuel level through the side of the tank.

Roy, I would LOVE to use fiberglass tanks. Unfortunately they only come in a 12" diameter version. All the different capacity tanks are based on that diameter. My propane well is just under 11" in diameter so these tanks do not fit.

I also like the idea of a 1 lb tank in the dinghy for portability sake when I don't plan on going very far.

I might eventually run three different tanks - 20 lb fiberglass on the rail used for refilling the other two tanks, a 10 lb aluminum tank in the propane well and a number of 1 lb tanks for the outboard and for the kitchen at home (for browning stuff). If I have a longer trip going with the dinghy I can take the 20 lb tank but it's primary purpose would be to fill the other tanks.

[Roy M]

You can get hoses and adaptors for connecting the outboard directly to the 20# bottle and lose no options.

[Roy M]

You will have to stow the tank on the correct side when in use with the outboard so as to convey liquid propane to the outboard carburetor. And the same configuration would be needed to fill your other tanks. I use 20# aluminum tanks (2 of them, minimum) for my domestic propane supply, but those provide vapor, not liquid, to my stove in their horizontal mode.

[Roy M]

Sorry, I'm not sure that your size Lehr requires liquid or vapor for carburetion. That would determine the appropriate orientation of the pickup tube.

Roy, I think only the 15 needs liquid propane to supply full power. The smaller motors should run fine on vapor. If it's really cold, and the tank is almost empty, you might have trouble getting enough vapor to run the smaller motors. Just turn the tank over and feed them liquid, they all will be happy with liquid propane.

An interesting question arises here .... you say that the 15 hp Lehr requires liquid propane. Does that mean that a standard propane tank (that when standing upright only dispenses gas) will not work with the Lehr 15 unless you turn it upside-down ? Does that also mean that the Lehr fiberglass tanks dispense liquid rather than gas ?

Going back to the refillable 1 lb tanks, can anyone tell me if the refillable 1 lb containers are made of brass? Are the threaded fittings on top made of brass? Are both (fitting and tank) made of brass ?

I've never tried running a 15 on a regular vapor tank but i suspect the engine would start to stumble if you try to go beyond about 3/4 throttle.

Only the thirty pound forklift Lehr tank is designed to supply liquid. The 18 and 11 pound tanks supply vapor just like the common 20 pound steel tanks.

When I saw the refillable tank in Home Depot, it looked like the threaded portion was brass and the tank portion steel. I didn't have a magnet to test this.
