Hello All, Hope someone can maybe shed some light??
89 GQ Patrol tb42 Pet/gas
Was out bush last weekend & running on Gas, on the track out I had a Couple of Backfires (Pop through aircleaner sound) So switched back to petrol, All fine, On the blacktop I switched back to gas & was running fine until It just cut out without warning as I was cruising to a stop. Tried to restart on Gas & it was cranking over but it was like the lpg was empty? I knew there was @ least 1/4 tank though. Switched back to Petrol & ran fine & as normal. On the way home I stopped @ the servo & put $20 Lpg in just in case the tank gauge was faulty? Still cranks but as though there is no lpg?
Thinking it was electrical?? I have searched through as much as I can see All electrical side of things seems fine, when I flick it to gas I can here the solenoid clicking over. I switched it over to gas straight away while still on petrol in my driveway & it usually splutters until petrol runs out & gas cuts in but just ran out of petrol & died! Ok I am thinking now Converter??? On the converter I found A screw?? with a flat head with a spring under it which I can just loosely press in & out?? this is on the flat side of the converter which has no connections to it?
All other connections to the converter seem fine..
Also, the past few weeks I have noticed when running on gas (especially with air-con on) If I put the accelerator down quickly it hesitates & surges??
Ok, Hope someone has the solution???
Thanks Pete

Will not run on Lpg
HI Kyle, Yes it does Mate, I have checked all the wiring around the tank as well & all seems Ok, All earths are fine & wiring is not frayed or loose at all from what I have traced??
About 300mm from the tank the wires are in a rubber tube to about 300mm from the converter. Don't see how any wires could have a problem from the tank to converter as they are concealed very well from any possible damage?? Although the lpg system has been in for over ten years??? Replaced Tank & Converter 3 years ago though.

When it backfired it might of wrecked the diaphram in the mixer and could be sucking air in. I played with the mixture screw on mine and adjusted it
to much and it showed no sign on firing. And i think correct me if im wrong
but the mixture screw on top of the mixer adjusts the air gas mix.
cheers joe

God of Magnificant Ideas!
Why is it ppl find LPG so hard to service ????
If it was a petrol problem ......... how would you go about solving the problem ????
You'd drop a fuel line off @ the carby /injector rail and check for petrol wouldnt ya
SO...................
crack the LPG supply line nut on the converter & turn the key to the on position breifly ...... there should be a shot of liquid gas squirting out.
IF NOT then you have a problem from the tank to the converter.
IF there IS a shot of gas then the problem is converter to mixer.
WARNING: do this in a WELL VENTILATED AREA with NO NAKED FLAMES OR SPARKS.
------------------------------------------------------------------------------
To check the converter disconect the supply line at the mixer,
turn the key to the start position and have a mate "smell" for LPG
If no smell is smelt then the problem is in the converter
if LPG is smelt then the problem is mixer related.
WARNING: LPG sniffing is not recomended
------------------------------------------------------------------------------
Things to check:
Electrical bad earths in tank / converter solinoids ( common )
Crushed LPG supply line from the tank ( occasional )
Blocked solinoid filter ( rare )
Converter "waxed up" ( common )
Converter diaphram broken ( occasional )
Mixer diaphram broken ( common )
