Holden Frontera - Additional Fuel Tank

HI,

I don't know about a quick fix on that one but there is certainly space to fit one behind the rear axle. I was told some time ago by a guy on the Isuzu website that it apparently is an anti collision requirement in the US for the tank to be in front of the rear axle to prevent it being ruptured in a rear end collision.

In the US it is still manufactured and sold as the Rodeo, nothing like standardising names hey. Do a search on Isuzu Rodeo and you will find out a bit. In the UK it is sold as the Vauxhall Frontera so if you google that you will also get results. It is all the same car which is made by Isuzu and it enjoys good sales in the US and UK but didn't do as well in Australia. GMH decided to drop it and the Jackaroo in favour of the Adventra program it appears and from what I can gather that has been a big backward move. Currently the only new real 4x4 by GMH in Australia would be the Rodeo I think.

The Vauxhall version comes in either diesel or petrol as well.

You hear a lot of rumours that GMH are about to go back to something to fill this gap but I am not sure what it will be as yet.

Hope this helps a bit.

I'm not sure which year Frontera you are talking about (guessing the wagon shape) however I have this info.

On my 1997 Rodeo the fuel tank is on the drivers side under the tray. However there are mounting holes in the chassis rails behind the rear axle which line up perfectly with the mounting holes in the Jackaroo/MU/Frontera of the late 80's/90's (maybe other years???). Some of these rear tanks had brackets that welded to the chassis but others bolted on. So go for the bolt on brackets. However to fit the tank you would be need remove the spare wheel winch.
Another problem would be the filler. The rear tank is standard on the Jackaroos however there was an optional second tank which sits in the same position as my original Rodeo tank on the drivers side. These twin tanks had twin filler doors. So you would either need to fab a system which filled both from the same filler or do some panel work.

Fronteras are also sold as Rodeo, MU and Amigo I think.

Hope this helps.

From what I've seen driving round, 2 door ones are Amigos, and the four door is a Rodeo, see quite a few round here, New York, and some monster local built 4X4's.

To your fist Q...no there is no quick fix to fit a second tank and it all depends on how much you want to pay or how handy you are at sourcing the required items as to whether its affordable. Yes I do believe a Jackaroo or MU(smae as Jack) tank would be a near on bolt up fit..nothing a tape measure and your time couldnt determine for sure.
As to filling it....you can get duel filler pipes fitted to your original flap, expensive and labour intensive. You might be able to get a second filler outlet installed in the side of your vehicle, ie mirror the original one..again fiddly and expensive.
As to whether you can get a Y pipe fitted into the standard hoses will depend on the angles etc and Im not convinced on how effective that would be when it comes time to fill up.
You can get very good quality muliti tank change over solenoids, that also allow the fuel sender to swap signals and the tank supply at the flick of one switch.
So as to your question..yes it can be done..but done easily...I dont think so, it will be complicated but it all depends on your determination!

Goodluck with it!
Matt.

Just adding my $.02 worth here.

In Japan trhey are known as an Isuzu wizard and there are quite a few imports of that name around in NZ but they have the spare wheel put down there.

Seeing as the price of petrol is going up and up have you concidered a gas conversion. A few years ago I found one in the eastern suburbs of Melbourne that used that space for the gas tank.

If you find a regular tank that fits in there let me know.
