Hi crew!

Recently new to owning a 60 series (purchased only 2 weeks ago) from interstate in Australia. Needing to get a roadworthy certificate in QLD.

60 is a FJ62 with 3F and LPG, the LPG tank has been removed by previous owner, and I need to get all the LPG pipes, etc removed before I can get it signed off by an LPG specialist to say it’s been decommissioned.

Not many Mechanics are interested in doing this job, from other groups apparently it’s quite easy but I can’t find any information or help, so hoping this forum there’s some legends with experience in this space!

See attached photos of engine bay, and underbody.

I’ve sent photos to a mobile mechanic of the piping that runs underneath but he seems to think that’s not a LPG line but a fuel line/breather, but is directly under where the LPG tank would have sat and runs to the engine bay. There’s no copper piping or anything running under the 60.

Cheers!

Seems like it would be a pretty straight forward job to me. Remove the carb gas adapter (AMOS GAS), disconnect and remove the LPG vaporizer, and then remove any piping and hoses connected to the vaporizer.

All of the factory fuel lines are on the right side (from the perspective of you sitting in the seat) of the vehicle.
 
I imagine getting it set up to run gas will be far easier than getting it certified straight petrol.

Given it's cheaper to run on gas than petrol , why would you want to remove it? I ran my LX mostly on gas, but occasionally on petrol just for the power (though I preferred the way it ran on gas , honestly). It ran well on either , but the oil stayed much cleaner on gas. You've already got the certification for the gas system and you can choose to run either gas or petrol.

Any gas conversion place will repair the existing system you have, but I think it'll be tricky to find anyone to certify it to be removed. You might also wind up being liable for any of the back rego expenses if it's like South Australia , because vehicles on gas are cheaper to register than straight petrol.

@Lead Head the issue in Australia will not be the ease with which one can remove those items, but the difficulty one will have in getting it certified for the government to sprinkle holy water upon it so that it can be driven.

Converting back to straight petrol from gas will have the added difficulty of gas being seen as a green fuel where petrol is seen as a dirty fuel.

Thanks mate. Which part is the LPG vaporizer?

Don you know if the image attached a gas line?

Thanks mate. I currently don’t have any certification documents for the gas. I’ve found a mobile guy to remove and supply the decommission slip for about $500 which isn’t too bad. But I can remove myself and take photos and send to a guy and he can provide me with the decommission slip (for $100ish).
 
The hoses/pipes which you show running on the outer side of the chassis are not original. Therefore, only you can see where they go and what they carry.
 
pretty certain the round circular piece between the carb and the A/C dryer on the left fender is for LPG
remove it an everything going to and from it should satisfy the inspector.
