Hello All,

What are the tips and tricks involved in getting a 2005 V8 Discovery that was converted to LPG running again? The car has run out of gas and from the owner's description it sounds like the car has not run on petrol for a very long time - prior to it running out of LPG.

I am not sure whether these LPG conversion allowed dual fuel options like my old Holden used to? Were the LPG conversions done on V8 Discovery's dual fuel or are they just dedicated LPG?

The car is currently sitting in a paddock well outside of the closest town to it. This means a car trailer ride to the nearest service station that sells LPG.

If there was a dual fuel option on these LPG conversions - it sounds like the petrol system went the way of many dual fuel systems - the owners neglect the petrol side of things. Petrol fuel pumps dry out, fuel lines crack and carburettor seals dry out and crack too.

This message is some research about whether to look at buying this vehicle or to go down another road in the future. At this stage I only have a Facebook notification about the vehicle that included a brief description.

Kind regards
Lionel

Avoid. My guess is it would be dual fuel as the engine most likely starts on petrol and switches over to LPG once it has warmed up. In any event, the LPG tank would be coming out of date this year and would need to be re-certified for a roadworthy.

LPG is also becoming hard to source.

LPG is also becoming hard to source.

We recently pulled all the LPG systems out of two of our work vans as it is such a pain to find these days.
It also reduced the weight of the vehicles considerably,as the LPG auto tanks are very heavy.

Getting the tank retested would be the least of your worries.We just drop it out ourselves,and take it to a guy who also does our refrigerant bottles.
They generally come out very easily,and reinstalling is just as easy,just need a trolly jack if it is under the rear,as ours were.

What brand gas system is in it?
Parts for some brands are difficult to source.
At a guess i would presume it is gas injected,depending on brand,if you get more than 250,000 Km out of the injectors you are doing well.
Most of ours started to play up at the 240 to 250,000Km mark,others went to 350,000 with no issues.
Ours were all Landi Renso,Toyota factory fitted.

Hello Scarry,

I crunched some numbers and it became clear that I was jumping the gun. I will cool my heels until I have my Defender 110 on the road to use as my own tow vehicle.

The cost of hiring both a heavy duty - 3.5 tonne car trailer and a vehicle to tow it with beyond the 300 free kilometres makes the whole scenario uneconomical for a $1500 - $2000 vehicle. Once I get my tow vehicle on the road the cost of just hiring the trailer makes things far more viable for lower value vehicles to be used in a project.

Kind regards
Lionel

Hello Dave,

Thank you for the immensely kind offer. I did contact the owner again. However, I have not received a reply. I suppose it is one of those 'all in the goodness of time' type of things.

See what pans out. Watch this space ... [bighmmm]

Kind regards
