HI there , i am guessing you are talking about when the vehicle is on LPG ? BIG PROBLEM!! lpg is a gas and will mix easly with the air BEFORE it gets into manifold then cylinder - so if your parking and the wind is blowing INTO the snorkel (or accross ) it will stall your motor as the gas/ air ratio changes.

I have had this problem with my work van - on very very windy days --- the wind will stall my van when parked at trafic lights, and thats with an enclosed airfilter UNDER the van away from direct wind forces

solution - snorkel wont work with LPG as effectivly as it would with a diesel motor. maybe best to dump this idea of a snorkel ( presuming its on a petrol vehicle )

I have spoken to my gassy and he claims it is a common problem. If I reverse the snorkel it stops the vehicle stalling, however it still runns like crap and uses twice the gas. Gassy recons he can cut piece out of snorkel and effectively make the snorkel a partime snorkel. He will develop a piece that can be clipped in when snorkel is required It will mean i have to fit piece back in everytime i go bush, "not happy" This concerns me as i think it will be difficult to create a water tight seal.

Cheers boys

Hi Kaymar,

I think you may have to explore further for the problem as I have had an 80 series 4.5 litre Dual Fual and my brother and dad both have 100 series on gas. They all have had Safari snorkels fitted and the cars have never stalled or had any issue whatsoever.
I have got no idea what the problem might be in your case but the "gassy's" diagnosis seems a bit far fetched to me.
One thought may be to explore a different chip for the computer to suit LPG or Dual fuel application.
It seems more like a mixture or a sensor problem to me. Maybe the "gassy" has played with one of the sensors like the air flow meter or oxygen sensor. Also LPG will usually idle slower than petrol so it is normal to have to bump up the idle revs a bit to suit the LPG. They will just be a little bit high on petrol thats all but only by a 100 rpm or so.

My brother and my best mate are both licensed gas fitters in Qld and NSW so I will run this by them and see what they come up with and get back to you.

helo kaymar
I have an 80 on lpg and safari snorkl, all ways runs well. last week i had a unichip fitted with dual mapping,makes a big difference.But anyway the sales guy at auto tech where i had the unichip fitted used to work for safari he was saying it is not a good idea to snorkels with lpg systems, as it gives them a positive pressure.
And safari dont recomend snorkles for lpg.

It's amazing how many gas workshops don't have a clue!!!!

As GQ PAT states above it just needs a balance pipe fitted between gas converter and air cleaner to balance out pressures it's that easy!!!!

Big Woody replied:

Hi Kaymar,

I said I would get back to you re: your issues with LPG after fitting snorkel.

Before I had even finished explaining to them the problem they both said it was a simple fix with the balance pipe as mentioned by other posts.

They said it was not quite as sensitive as other blokes have said just tap the hose into the air intake syatem before the aircleaner and run it around onto the other side of the diaghram and it all shopuld work fine.

Let me know how you go.
