Re: Second Fuel Tank Capacity

Hoooweeee, looks like this guy is getting prepared for roo's with that 'nudge' bar. Long range tank suggests he's heading for Darwin or Alice????????

Both will compliment each other on them roads. emoticon

Re: Second Fuel Tank Capacity

Now that I have had the vehicle for a while, I have found a few problems with having the second tank.
Rear spring sag. I know this is quite common on all vehicles, but I only have to have about 100kgs in the back with a full rear tank and she rides low & bottoms out a fair bit. But as the tank empties she slowly returns to an enjoyable ride. I'm considering on upgrading the springs, but that will be after Xmas holidays.

Another is the location of the charcoal filter (Vapor Return canister) I no longer have mine as it has been beaten to death by rocks. The only thing I have is hoses going to a bit of plastic where it once lived. Not sure on replacing this as yet. If I do will have to mount a shield over the area. And do I really need it!?!

Tank Flow back. What has happen a few times is flow back from the front tank to rear. This only happens the front tank is over 1/2 and the rear has more than 1/8 in it. This is only a pain when I want to keep the weight away from the rear end (spring sag).

The fuel gauge reading full when empty. It seems when the fuel gets below 1/8 tank. The fuel gauge can jump around, from not so empty to full. I wish it was full. LOL.

Apart from the above, which really isn’t that much of a deal (OK maybe the springs) I find the fuel tank does what I need it to do.

Re: Second Fuel Tank Capacity

Hi Wally,

I fully agree with you about the suspension issue and the sag and in fact that was my very first comment to the guys at Sutherland Off-Road.

I guess it is not something you would want to use in your everyday city driving as 110LT of fuel is a lot of extra weight for the factory suspension to handle.

Suspension/springs upgrade is almost a must with this type of mod.

The fuel evap. canister is needed if you want your exy to still be compliant with fuel and exhaust emissions emoticon

Here is what is does

I can try and get you one from the wreckers if you like and I've seen many of them there.

Re: Second Fuel Tank Capacity

Thanks for the offer Jalal. I'm not interested in replacing it at this stage. But maybe down the track.

Re: Second Fuel Tank Capacity

Not really off-topic, I have been considering going LPG for a while now and looking at your setup Billie, makes me wonder whether an LPG tank would fit there which would allow me to keep the spare where it belongs. ( the LPG tank usually goes in place of the spare).

Re: Second Fuel Tank Capacity

Vinnie,

My understanding (and I could be wrong) is that it's a safety requirement to mount/position the LPG tank inside the car and not externally.

You wouldn't want to be inside that exy if you hit the gas tank and tear it going over a rock or something.

I have not seen an LPG tank positioned under the car at all. Look at the taxis for example and you will find that it is at the back too.

Re: Second Fuel Tank Capacity

Thank Jalaski,
Actually, under vehicle fitment of an LPG tank is quite common, and usually the 'normal' course taken in most 4wds, utes and trucks. They do have to comply with certain safety standards such as 100mm min ground clearance, tank shield etc. My Rodeo DC Ute was fitted as such also. The other factor is leakage. although tank valves etc inside vehicles have to be vented to outside air the possiblity of gases leaking inside the cabin is something that can happen. My objective here is to enable me to retain the spare where it is. Whether I can find a suitable tank to fit where the old muffler resides is another matter.... there may not be one. ;-)
Another hurdle is to find the optiminum in-line exhaust system, i wouldnt want a loss of power due to an ineffecient system. I wonder if Hi-Tech have any ideas?

Re: Second Fuel Tank Capacity

Thanks for the information Vinnie, for trucks I can understand and the same for larger 4WDs because there is plenty of ground clearance, but for sedans and SUVs, I am not so sure because I don't think we would have enough clearance there with a gas tank.

I am sure there will be loss of power associated with the LPG set-up, how much I don't know, but I can ask Hi-Tech for advice.

Your best bet would be to call an LPG fitter and they can tell you the exact details and possibilities.

Re: Second Fuel Tank Capacity

Thanks mate... If they have an in-line exh system ( cat-back) that they say will work with no loss of torque I'd be happy to buy it from them, that would leave room free for a lowprofile lpg tank, or altenatively the spare.

Re: Second Fuel Tank Capacity

Hi Vinnie, About mounting an LPG tank underneath. I would say that there is room, but the size of the tank would play a part. I have seen small multiply tanks in a row used before. This is where space was an issue. The bloke was carrying around 200 litres. By memory it was 5 tanks about the size of standard dive cylinders.
As for the tyre shape tanks, I haven’t seen them before. And I gather that you still want to retain your spare tyre storage.

Rough Dimension of the tank are 170mm high, 390mm length on the exhaust side, 520mm length on the other half & 820mm wide.

Hope this helps
