G'day fellas.
Quick question, does the lpg system screw with the engine after time? I read that it doesnt help with the heads? And would it be worth going straight petrol due to gas prices at around 95. Who do I talk to in Perth, and roughly how much am I looking at? I am slightly mechanically minded, so how much of it should I be able to do myself? Cheers guys, any advice is appreciated👍
You should be able to strip it out yourself, gas wrecks your heads , well the valve seats.
@ 95 cents I don't think itd worth putting in, straight fuel would be better for your motor too
big gas places like Supa gas will take your tank for free
I'd drive on gas until it runs out to try empty the tank as much as possible. Probably the most important bit is the petrol cutoff valve. You'll need to find this and remove so the petrol line is straight through. It should be near the carby. (yours ended up being a carby model didn't it?).
Generally the timing will be advanced more for gas and also it will probably have spark plugs suited to gas so these two will have to be put back to normal.
Normal petrol only timing should be 10 degrees, +/- 1 degree.
Recommended plugs are:
Standard type: BP5ES, gap 0.8 - 0.9 mm.
Obviously any holes left by gas lines you remove from the air intake will have to be blocked. While you're there give the carby a once over with some crc etc and make sure all the linkages are moving freely.
And Ofcourse be aware that any leaks are highly explosive!!
By all means ill give it a go, but im used to servicing dirtbikes hahaha. Would I be better of putting a long range petty tank on? Where would I get one for the right price? Cheers guys 👍
Check ebay for AUX or long range tanks.
I have a 75 ltr aux tank frm Brown Davis
give Kevin a call for a price
In melbourne lpg is at 80c and its still worth running - but not worth converting a truck to lpg
Make sure you truck is running properly on petrol - does it idle ?
Depending on the lpg mixer - you might need to purchase a standard air cleaner.
You could leave the lpg gas switch and petrol solenoid in as an ant theft device?
Turn the gas off at the tank (theres a valve. Carefully crack the gas line to the mixer - you should only get a short burst of lpg - i its constant you have not turned the tap off at the tank.
You can safely remove the tank, gas lines, filler (it has a one way valve at the tank), convertor and mixer - you might be able to flod them on evil bay if the tanks in date.
Just get in and drive it first mate. After a while you'll figure out what mods best suit your needs. No sense going overboard straight up.Quote:

Usually when a gas tank is fitted to these they put it where the factory petrol tank is and therefore fit a new aftermarket petrol tank to under the middle of the car. More often than not that aftermarket tank is bigger than factory.
Trust me guys, ive been reading everything I can find on what suits and what doesnt ect. As ive read plenty of times from different sources, ive found that lpg is crap, and especially for an everyday car running it, I dont want to keep giving the car a head job 😞 so thought id play it safe and remove it all together? Save some coin in the long run to do some well worth mods ive got in mind :D but it just doesnt seem worth the hassle of running gas at 95 cents p/L. My dads 98 gu 4.5l patrol had a gas convertion a few years back, he says its the worst thing his ever done! He done it back when gas was heaps cheaper, so back then it made sense to do it, but now its not.
So is the whole process off removing it easily enough done by myself? I know how to undo a bolt if that healps hahaha. Thanks guys!
sound like you have already made the decision, as the boys have said..
drive car untill lpg tank is well and truly empty.
then turn lpg valve off at tank.
remove what you don't need any more.
fix any lpg installation holes etc
if lpg tank was under body, fit a std or long range petrol tank.
how far you intend to drive on 1 tank should determine your useful tank capacity, "personal preference".
service carby.
retune car.
sell off tank etc.
looking at doing it myself also.
So many closed minded people. gas isnt as bad as people think. 99% of the time its the dodgy bloke that fitted a cheap crappy system. yes the head will last longer if not run on gas but i bet youl be pulling a head off a tb42 to fix the water galleries that have eaten into the head before you recess the valves from gas. one great advantage to gas on a 4wd is itl run on any angle so if your climbing a hill for example it wont run out of fuel. Even with todays prices i worked out im saving $9.60 per 100km by running on gas over petrol atm. but if you really wanna take it off its really not hard. just as the boys have said if you take the petrol lock off and just have the fuel running like normal to the carb all the wiring will be able to be taken off as all the gas switch does is turn off the petrol lock and turn on the gas locks. then simply remove the rest of the system.
