LPG/dual fuel VEs thread . Tips tricks?

[BADTR1P]

Well,plenty servos in Vic/ Melb. also I drive to and from NSW every Xmas,just about every servo on Hume has lpg..So it'll be awhile b4 lpg pump's disappears (at least this side of the country anyway )

Ah this was south west regional vic to gold coast going thru dubbo etc. Only passed a few LPG pumps along the way. I could have pulled up a servo map on my phone I suppose and would've been alright.

Anyone experienced LPG smell in cabin while LPG in use and sitting at traffic lights? Happens 50% of the time. What could the issue be? Trying to get an idea before I take it to a specialist.

had similar on our VE dual fuel, the lpg lines to injectors(rubber) has a perished a bit on a joint, cut end off and pushed back on all good. Its low pressure so easy to fix. found the little bubbles with soapy water spray.

Well I think I found the leak. There's tiny pin prick holes on two hoses near the clamps, along that hose that has a t piece connector on it. Can I replace these myself? I can hear the lpg hissing out of it and smell it, and can physically feel it when I put my finger over the hole. In 2nd pic you can see tiny hole to the right of the clamp.

You probably can replace it yourself, you’re just not legally allowed to. Gas lines can only legally be worked on by a gas fitter.

Okay thanks. These don't seem to carry too much pressure. I would assume with engine off theres low pressure in them, especially considering the gas leaks from them for a few minutes after engine is off after that I would assume there's no pressure at all. Looks like simple fuel hoses and clamps. Seems safe enough but I know the legalities around it.

Turning the tap off at the LPG cylinder while the car is running on LPG (letting it stall from lack of LPG) will burn up most of the residual LPG in the lines.

The electronic solenoid does shut off the LPG whenever the car isn’t running but it’s best not to rely on only that to keep the high pressure LPG at bay.

Thing is though if you don’t have the proper hose clamp tool to fit the proper clamps (like what’s on there now) it might actually be more cost effective to just get an LPG mechanic to fix it.

Also there are liquid phase and gas phase LPG filters that are supposed to be replaced every 15,000kms so it might pay to get these done as well by an LPG mechanic.

Yes, gas lines can only be worked on by a gas fitter

But surely it depends on what the definition of gas line is else everyone who has a bbq at home will be in the poo when replacing the hose between the lpg bottle and the burner or replacing the seal/gasket at the bottle side of the hose.

Sensibly, I’d suspect working on the low pressure side of one bbq or their automotive lpg system may not be so naughty but whatever one does, one should take care, learn best practice and show some sense about how they approach the work.

Best one doesn’t smoke while while faffing about with any flammable gas or fluid

Something I've wondered is what happens if you drive on lpg until empty? Does it switch to petrol automatically? If so how much lpg is still in the tank when it happens? I've always manually switched it once it flashes and beeps to signal it's near empty.

Apparently it does automatically switch to petrol once the LPG runs out but I’ve never tried it myself. I always switch over to petrol once it starts flashing.
