Outer Limits 4x4 Board

If your running a vehicle on straight gas, is there a way that you can fill it up in the scrub. With petrol/diseasel you can take jerry cans, what can you do for gas?
Excuse my ignorance if this is a basic question, but as far as I knew, you weren't able to run fittings to allow you to hook up another bottle.

i made my own jerry can its a bbq bottle, all i did was make a hose so i can fill my tank with it through the normal gas filler in the side of the truck. youll find just about all taxis have one there highly illegal but u can buy the parts from supagas ill post some pics if u want
cheers

Rob, some pics would be appreciated. I'm starting to really think that this way is the go, but we don't have too many servo's with gas up this way, which makes things a little difficult if you want to venture away from home.

does this really work? i would have thought that the bbq bottle and the gas tank would equalize in pressure, not empty the bbq bottle into the tank, there by only getting you approx 4.5kg into your tank out of a 9kg bottle.

Taxi's do it when they for get to fill and run out. Its enough to get them out of trouble.
Maybe a forklift size bottle would be more suitable.

yeah it works. you tip the bbq cylinder up side down. the pressure will equalise but the fluid will run down into the tank. hey rob... wouldn't mind a listing of part numbers if possible.

What you are talking about is called decanting. This is generally carried out by using a liquid withdrawl cylinder which has an extended dip tube to collect the liquid from the bottom of the cylinder. Turning the cylinder upside down on a vapour withdrawl valve will have a similar effect. This practice should not be taken lightly as Propane, which is the main component of LPG changes state from liquid to gas at -52 deg c. therefore you have -52 deg liquid that can A- freeze the valve open leaving you in crap & B if leaking expands 270 times its own volume leaving you in crap with a possible cold burn. I personally would prefer a jerry leaking fuel in a rollover, than a bomb leaking. Do yourself a favour & forget carrying Lp in or on your fourby. I have had lots of experience with this sort of stuff & hate hearing about the bad stories. If you have a fuel carrying problem, get a diesel. ps sorry to be a party pooper.

For anyone who has seen pete antonacs new buggy, i like his swap and go bottle mounted on the front.

I used to drive fork lifts before licensing days
They had quick change over bottles, was an easy thing to do.
Safer than messing about with bbq bottles.

Geez, the people u meet on this forum.

The only other thing I can think of is that BBQ bottles don't have any external venting making them a bit dodgy for an extended period of time in the car i.e. sitting all day in your fourby at 70 degrees I don't know what they do when they have to purge the pressure ?? anyone ?

can make a hose to fill them from the lpg pump instead of the rip off bbq cylinder fill thing. we also use lpg instead on our oxy.

As you know it does work but the car stuff is nowhere near as clean as the BBQ refill stuff - your burn temp can change quite a lot hence the fine for filling them that way.

Having said that I know people who have done it for years - not a choice I would make but each to their own.

Pretty sure Gonads ran a similar setup on his zook buggy.

Gonads old zook, the one he sold to Athol was Forklift bottles

Can you fit forkbottles and be road leagal in NSW ? .My work has a few floating around

Yep bbq gas prices are a rip off, we use about 10-15 45kg bottles a year to run our furnace and cost is about $75 a refill, a 9kg bottle is something like $20 a bottle. I was of of the understanding they are exactly the same contents as per LPG for cars which is 45c/L? We now use a 1/4 full 45kg bottle on the bbq at an angle and yes if you get liquid into the regulator it freezes it and stuffs the diaphragm and also seizes the bottle valve open. We have a 16kW burner on the furnace and often freeze a bottle and lose pressure and then change over to another bottle. (bottle heater yet to come) The cheapest gas is at the servo so if you bodge something up you can happily fill either 45kg or 9kg bottles as long as noone sees you as i believe many thousand of dollars fine. We only this week got the fittings to decant the near empty 45kg bottles into near full ones and is easily done due to there being a bleed valve on the recieving bottle. A car tank however i am not too sure on but isn't the fitting you use to fill it also the bleeder so if you can get it you shoud be able to do it happily.
Why be worried about an lpg bottle in the back of your car it is under the same conditions as your lpg tank and have you seen how many times higher the test pressure is than the fill pressure.
