I dunno how you blokes do it.. Between me and my father in law we did half a million km in two 80 series cruisers running the old fumigation systems without issue.
You know is such a funny situation ,same car ,same engine ,same lpg system and they both run differently. I have heard this story so many times Joff. It really does seem to have no ryhm or reason.
dad worked in a panel shop years ago and the boss had taxis as well he gad 4 falcons on gas 2 ran like poo and 2 ran perfect ,they could never work it out.
FFL,
only piece of advice I can offer is to install a back fire valve .They cost around $100 and they hav a one way flap in them so when /If the engine backfires on LPG it does not explode your air box and lid . They are not cheap to replace . I have a valve at home that came off the cruiser . If you want it you can have it mate (i drink XXXX) . they really are worth it . I wish I knew about them before I blew the box up ,twice.
I only ever got 300kms out of the 70 lts on the h/way , so if you see the 4-430 you might be running lean and I would ask the gas techs to adjust the mixture for long term engine survivabilty rather than short term economy as it's running them lean that causes the head to go south. Also the valves seats in the factory head are not designed for lPG (aparently)this is why the head sufferes so badley from lPG use hence the upper cyl lube kit which I only found out about after the fact. But with yours getting adjusted it might cover that. Also get regular tune ups they never stay in tune long term and you will see this through your economy when the k's drop shes running rich and it works out cheaper to get a tune than burn LPG.
I don't want to be a sour grapes poster ,mine ran like poo but thats not to say that yours won't run like a dream as Joff posted,if she starts to play up at least you can get on top of it with a little knowledge from my bad experiences.
But enjoy the economy and the fact that your vehical has less carbon emmissions than most so your green creds are there mate, also you will notice a difference in economy with different gas suppliers ,I always found VITAL GAS was the best and cleanest to run.
All my comments are based around my gas system and do not represent LPG systems as a whole ,so I am not bagging them out totally just sharing my experience.
the only thing to check is that they wired the fuel sytem as the defult on the soliniod thingy , my idiots did not and when the soliniod went I could only run gas as it cuts the power to the injector rail and you get no spark and then the convertor crapped out and left me stranded . when the new one went in they got it right.
Best of luck mate
