Dual Original tanks

[SPB]

It has been mentioned briefly of mounting a second original 75L tank on the opposite side to the original.
I have had a look at mine and there is room. The only problem is the muffler needs to be moved and the exhaust rerouted a little. There is room for the muffler under my tray(dual can trayback) near the spare tyre.

Getting someone to do the job is no problem. Now looking at the MVR regulations I probably need to get it Engineered which seems to be the only hard part. I will be going to the MVR next week for an in depth chat to confirm that it can be done according to the regulations.

I already have the tank/sender/gauge.

How it feeds (as an AUX and pumped into 1st tank, run as twin, independantly) is just trivial at the moment.

So.... Has anyone done this. I would appreciate any tips/tricks lessons learned.

it is just more than moving the exhaust.
The drivers rear shock also is going to be a problem.

when I looked at it I figured that I would have to cut the tank to fit the shock and have clearance.

In the end it was all too hard

[TUFF TROOP]

Have you thought about a poly tank under your tray. That's what I'll be doing to feed my 125lt tank.

Actually purchased a second tank, for $20, to do this and realised it wasnt going to fit. Had a mate available to do the cut and shut.

I even went to the extent of purchasing a solenoid operated fuel valve with sender unit switching for the feed to the engine

I was going to fill from the original filler, with expansion pipes, overflow and venting hoses just T'eed in to the originals. Routing the filler pipe over the exhaust was an issue as well.

Got a brown davis long range tank second hand for $400 so it all got canned.

I would stick with the long range tank as there is more than meets the eye in little extras, engineering weight shift right & left side shocks side specific, & who knows about crash intrusion points air bag sensors etc ? If you can find a second hand tank like age9111 for $400 would be to easy. Good luck if you do go ahead make sure to post plenty of updates & pictures of the mod.

Yes, I had a look at this, long time ago. The only way I could see it working was to get a tank from a LHD Triton which would fit straight in but then there was the problem of fitting the exhaust down the middle and that would have needed fabrication of some serious heat shielding. Lack of availability or the cost of importing a tank, plus the heat shielding issue mad me decide it was all too hard. If I really need a long range tank I'll just get an off the shelf one.

The other issues raised above - side specific shocks, weight, crash intrusion points, air bag sensors etc. do not exist. Shocks are not side specific, weight is only 80kg, and being inside the chassis rails the extra tank would have nothing to do with crash intrusion points (what is a crash intrusion point, anyway?) or air bag sensors.

Chris, the drivers side shock is forward of the rear axle- this extends into the area that the fuel tank requires

(what is a crash intrusion point, anyway?) or air bag sensors.

Crumple Zone??

I've been hit from behind pretty hard in mine. Nothing really crumpled

Thanks Everyone,

Over the next two weeks I will talking with the Engineer and the guys doing the work(Im sure as heck not doing it!) If in the end it can be done is price comparable(Ill accept a % +/- expensive).

Will keep everyone posted.

Without running your exhaust over your tailshaft and rear facing the driver side shock an original tank will never fit

I'm almost certain that the shock faces opposite to the other side for a reason and if it could be changed would just create other problems

The money and effort involved would be far better spent in a replacement long range or auxiliary tank.

As others have said they've looked into it and I'm just another one

[SPB]

Well today I went to find someone who can fit the dual tank for me. The first guy can alter the fuel tank to fit around the rear shock. I will lose about 5litres.

The second guy can finish the job. Reroute the exhaust, fit the tank(connect it anyway I want it).

Both have told me I do not need an engineer as they are nothing doing that affects the cars handling or altering the chassis. Both are reputable businesses. The second does a lot of custom work and looking at what was in their car park I reckon they do good work

Cost:
Fuel tank: NT currency(carton of beer)
Fuel tank alteration: $150
Exhaust reroute and fuel tank fitting: $800 in 2 inch or $1700 in 3inch stainless.

So cost wise if even if costs and extra $500 I think it is worth it, considering how much a long range and fitting costs.

So next week its trip to the MVR to confirm the viability. Its looking good.

Missed this Sel. Yes, I know. The LHD tank is a slightly different shape at the back.

Good to see that SPB seems to have found a solution. We need pictures when this job is finished.

[SPB]

Well today I saw the MVR. Showed them my diagram and the car of what I was intending to do. No problemo they said. As long as it complies with the standards which everything I intend of doing does.

No engineering required whoo hoo.

Next problem is I forked out $3K for tyres yesterday and I have to speak to the minister for finance again! So I think this will all take shape between now and April. Pics will forthcoming as it progresses.

[mattz]

3k for tyres.
What did you get........that's like $600 a tyre inc the spare.
Or more if you only got 4.

[SPB]

Sorry Should have said thats 6 for the car( I always have 2 spares ) and three for the CT. All BFG Allterrain.So 9 in total.

[mickkk]

They sell tyres up here by their weight, they generally base it on the current rate of gold.

Phew.......I was a bit worried as I'm due for some soon.


3k for 9 tyres......it ain't to bad then.

[SPB]

Okay so after a brief Hospital stay I now have the fuel tank reshaped. A big thanks to Ross Caswell at Casweld in Yarrawonga. I have lost around 6 litres from the look of the photos with the 3L Milk container. But with the filler hose being longer I might regain a litre or two. So I just rang the guys doing the install."So when can I book it in?' thinking it might be a week or two."Tomorrow at 8am" NO PROBLEM. So all things going well by the weekend it will all done. Just in time for my Easter trips and the school holidays.
Note to Moderators: This will also be going into my build thread. So do you want to redirect it or leave as is as it is a little different from the usual long range fuel tank setup?

[Thommo3337]

Awesome!!

[Cowboy Dave]

I reckon put it in this thread as well. Makes it easier to find later.

[SEJ GLX-R]

Good work
Now you have me wondering if this could be done with a long range fuel tank in the original position

[Snooozy]

If anybody else wants to try this & would like a free std tank to play with, check parts for sale or PM me

[har05l]

I'm keen now to see how the exhaust is going to be fitted

[RHKTriton]

Does the exhaust actually have to go over the axle?

I'm pretty sure the outlet only has to be past the rearmost opening window or vent - so could it be
pointing out before the back wheel?

On my old Rocky thats how I had it and never a problem.

[Kegsy]

In nsw it has to be 300mm past the last cabin opening.

Ie door, window, hatch etc. So pretty much 300mm from the rear cab window.

Also it should exit the body of the vehicle not just dump under the vehicle. However an engineer can certify under vehicle exit if they deem it satisfactory, with a ute its normally not a problem.
