Does anyone have a 100 series V8 converted to Dual Fuel - Petrol / LPG.

I am interested to know if it is worth it? Where is the tank located? Loss of power??
Loss of clearance off road?

Any comments would be helpfull.

Cheers

Dave

am about to go lpg on a 6 cyl 100 series. A search thru the archives and Google backed up what the installer reckons I can expect. Some claim 16ltrs/100 ks on petrol which I find a bit optimistic and 21ltrs/100 on lpg. Expect to use about 25% more fuel with lpg but the price diff means you'll be paying around half the money to travel your 100 ks or whatever distance. Looking around Sydney prices are about 116c for ulp and 42c for lpg. I did see some Shell servos charging 56c yesterday but most were lower 40's. You can do it two ways: two long/slim tanks under your side steps giving you 70ltrs usable and retaining your original tanks or, take the sub-tank and spare wheel out and chuck in a tank to give you 90ltrs. Bearing in mind lpg uses a bit more fuel the 70 ltrs wouldn't take you far and it'd feel like you're refuelling every 5 mins. I'm going for the 90 ltr tank (also retaining 90ltr ulp tank). I've been quoted 2,650 for the twin 70ltr tanks and 2200 for the 90 ltr. The snag with the 90 ltr is that you have to find a home for your spare wheel. My local4x4 outfit say they'll fit me a bracket in the luggage area for $180/200 where (especially using a wheel cover) I can store the spare or you can pay between $550 to nearly $2000, plus fitting,for a rear wheel carrier depending on whether you want to just carry the wheel or add high lift jack, spade, jerry cans and a wardrobe for the wife. Good luck.

btw, there's a slight loss of clearance with the two slim (70ltr) jobs and an actual gain of clearance with the 90 ltr 'cos you're removing the spare wheel which can be a bit of a nuisance with it's low-slung location. Loss of power on lpg is apparently negligable and cleaner.

Another option is something my friend has in his 100series 6cyl.

He has retained all the factory fuel tanks and spare wheel underneath. He got his gas tank put inside the rear cargo area on the LHS. It is up against the LHS of the interior mounted so you can see one end of the tank when you open the rear door. He had a custom drawer unit made up to suit which encloses the tank.

Don't know how big the gas tank is.

Hi Steve,
I have an 80 series on LPG and I made my self a false floor in the back on the vehicle to house the spare wheel. I Made it out of MDF for around $20.00. There is also room to put other junk in there like tool boxes, jacks ect. Aand when the tail gate is closed you cant see a thing and all is very neet and safe from floating about.

To continue, sorry, I have had spare wheel carriers on other vehicles but found them a hassle when you want to open the rear doors or lift the spare wheel up on the carrier. With the false floor you can lift the spare wheel into position much easier

Don't know where you live however, if you contact Ron at Torquegas (Caloundra Q), on Ph1800 801 120 it will be worth your while.

Following a tip from Cruiser (see post 21113) when I had consumption problems with my 80 series , I took vehicle to Ron and found him a wealth of knowledge re LPG.
L/C is now running better than ever and the fuel consumption, whilst not yet up to what he says it should be, has improved by 28%.
He has sent me a replacement part which hopefully will improve consumption figures.
He has been in the game for around 26 years so he sould be able to set you straight.

Ray: sounds like the answer. Did you just cut the top to shape and prop it up on legs/I don't fancy drilling into that plastic crap around the sides.

you did well to get your mdf for $20 mate. I've just fitted mine out $60+ for the timber and brackets. I've done it in two pieces (you wouldn't get it in any other way) running a 12" high support parallel to the back seats with the top sitting on that with r/angle brackets and the other piece has 12" (a piece of ply on edge) support running at right angles to the back seats. Only thing now is anchoring the bloody Waeco down. I'll be getting a cargo barrier anyway, and I'm gonna look for a nice piece of carpet to finish it off.
