Wondering about updating to a gu petrol, and I understand they all have duel fuel tanks. Questions - what size are the tanks, which tank is removed to fit LPG, and what's the cruising range with a duel fuel setup on black top towing a 800kg trailer? Thanks.

I'm a diesel jockey, but I know a bit about dual fuel set-ups as I had one on my 1990 Maverick many years ago.

The original 2 tanks hold 95 litres and about 34 litres. The main tank sits behind the rear axle and it is this tank that is removed to install the gas cylinder. The other, smaller petrol tank sits under the floor, beneath the rear, driver's side passenger area. You can also replace that smaller tank with one that holds about 80 litres of petrol. I think the gas tank holds about 100 litres of gas @ 80% cut-off (ie: the tank would actually hold 125 litres if it did not have the safety cut-off feature.

As for how far you would get out of the 2 tanks, I can't help you, but suggest it would only be about 500 to 600k's with standard petrol tank + gas and maybe 800 to 900 with the larger petrol belly tank.

Main tank taken out leaves you with 30lt petrol. That can be upgraded to a 70lt which I would highly recommended. Gas tank installed is a 90lt.

I get 320kms to a full tank of gas pulling a 5.5m aluminium boat.

Hope this helps.

my GU was on dual fuel when we bought it. The main tank has been replaced with the gas which gives about 90-95 useable litres (tank is 120 ish I think but can't use the last bit). The reserve tank (petrol) is supposed to be 40 litres but I dispute that. I have heard the sender unit is actually inside the tank and reduces the useable volume to about 35 litres. You can replace this smaller tank with one that is 80 litres but costs about a grand.

The gas is great around town but range when you head bush is a real problem because you can't get gas many places when you head out of civilisation.

If you do decide to get gas fitted I might be interested in your petrol tank and bits you have removed (I might switch back).

My guess is we get about 400k's on a tank around town.

40l could be right.

My Ti has a 40l Sub tank. 35 is directly useable , but , if you leave it for a few days , and because everytime the engine starts the subtank pumps works for a few seconds , it does actually drain the tank. I have fitted 40l into my subtank.

When I looked at a Dual Fuel patrol , I worked out that I could get 500k's tops , in the city , working on approx 350k's for gas , and 150k's for petrol.

Thanks folks. Hmmm ... so for touring range it's best to stick to straight petrol - 130 litres total at say 20lit/100kms = 650km range; whereas lpg is a bit cheaper and more accessible for driving around town, but doesn't get you quite as far on a trip. Does that sound right? It's a pity one solution doesn't achieve both needs.

Thats about it. I guess it depends how far off the beaten track you go.

I gather in some vehicles (Cruisers?) they can add a gas tank without removing either existing petrol tanks but this doesn't seem to be possible with the GU. Not sure if it's possible to get a smaller gas tank and replace the sub tank instead. In that way range wouldn't be affected quite so much. Would be a pain in the proverbial having to fill up your gas tank every 100k's or so though!

I used to own an FJ62 on gas, and even with the main 95L tank under the cruiser and the LPG tank in the rear cargo area of the wagon, my cruising distance on long trips was dissapointingly low for the amount of fuel I was carrying.

I think from memory the LPG was 85 litres, but I rarely got more than 360 klm out of it. Big motors like the cruiser and patrol are very heavy on LPG. If you head off up north where the gas ends up costing more than 70 cents per litre, it almost becomes uneconomical to run on gas.

Around town, no wuckers, cheap fuel and you can get it everywhere.
