Is it possible to have underslung LPG tanks on a RRC. I'm considering buying a Classic for work and would convert to LPG for economy but could not afford to lose the boot space.

Also is it unrealistic, even if I could get hold of a tidy example to expect it to last approx 5 years at 15K miles per year, towing a trailer for six months of the year without needing constant attention and eventually possibly an uneconomical repair.

Thanks for any opinions and the ridicule likely comming my way for such a sopy idea 'The wifes words, not mine'

But I might aswell run around in a smelly old classic all day instead of my smeelly old van!!
 
It wont last 5 mins withour needing constant attention, and if you buy one with anything other than a rebuilt engine which is healthy it will struggle to last that long on LPG from what I have heard on here and read in landy mags/books.

You have to like fiddling and have a tough wallet to run any range rover, the RRC is probaly the cheapest but its still hurts!

My 4.0 on carbs is ok but i had twin 70l tanks.
two small torpedo tanks do not give you the volumetric capacity to be efficent return on your money as the fuel saveing is taken up by extra weight.Twin big feckarf tanks in the boot make it economical but other than that yer messin about really.get a diesel.
 
Nah he got snowed in, and auction finsihed yesterday! u will have to give me yours now:D
 
Hi,
Noobie to this forum but I have been running LPG for about 12 years and completed 4 installations, all of which are still running.

Fett is right to say that you need a decent engine to start with. LPG won't damage an engine but it does seem to expose any weaknesses and is less forgiving than petrol. It is also fair to say that any RRC is a bit long in the tooth and will need constant TLC but they don't have to be unreliable.

My first installation used twin 30 litre underslung tanks because I got them for nowt and like you, I didn't want to use up boot space. From memory, slung from the floor, they didn't hang much lower than the bottom of the chassis but the main pain was the constant trips to fill up 'cos 60litres of tank gives a capacity of about 48 litres useable. The other thing is that two tanks are slower to fill.

Another alternative is to replace the petrol tank with an 80 litre underslung gas tank and a small 10 litre petrol tank. I did this on my '94 Disco and it was a pretty good compromise. I got the lot as a kit from the internet and it was a straightforward install.

My brother took a different route. He went for an upright torroidal tank to mirror the spare wheel. Ok, it was in the boot but was mostly taking up dead space.

Finally, just my opinion but 3.9s seem to run better than 3.5s on gas and to get the best economy..........fit a new camshaft.

Hope this helps,
Cheers
Chris
 
If you are thinking of buying a Classic and converting it I woudl say think again. I'm not at all convinced the cost is worth it, in fact, the cost of converting it is probably more than the car is worth an dwon't make it worth any more money in the future.

As for the other bits I would listen to the folks in here. I run an RRC and for the most part it has been pretty good but you are always waiting for the next "issue". All Range Rovers require high levels of maintenance if you want to get the best out of them. Don't get me wrong the RRC is fabulous and I am very attached to it but there are days when I would gladly dowse it in petrol and throw a match at it.
 
I am running an 89 classic 3.9 on LPG. Never had a single problem relating to the gas, apart from when the tank brakcet snapped off. (rotten sill). Still pulls very well on gas, system has been fitted for about 7 years and it is the original engine.
You may go through more spark plug though. Oh and always keep on top of the servicing.
I have twin underslung 36.5 litre tanks, giving around 56 litre usable capacity. Average is around 160 -180 miles per fill. They sit approx 1 1/2 inch below sill level.
Ignition timing will also need resetting to run the gas at optimum efficency.
