Hi @beau.sagadin. Sorry for reviving this old post. Did you ever get these water tanks made up? I am looking to replace my crusty Trakka versions and would be interested in the design.
Thanks.
Jon.
Hi Jon.
You could try Long Range Automotive in Lilydale.
2 years ago they fabricated and fitted a fuel tank and a water tank for me.
I dropped it off on a Monday and picked it 4 days later.
Very neat job…I love them…(the tanks that is).

Thanks John.
I have one of the tanks from South Africa, so no plans to build another. The one I have is designed like that (maybe one is a copy of the other?).
If I was to design my own though, I needed to add notches to the top of the tank to clear the mounting bolts for the (factory) middle row seat. This allowed me to pull the tank hard to the floor.
I also used 4 straps (not just two it came with), and I would have put 4 baffles in the tank to line up with the straps for added strength.
I also would have (internally) run the breather to the middle of the tank to stop surging down the breather when the tank is full.
I can’t remember the thickness of material in my tank, but it was quite heavy, and could have easily been made lighter. You could put a second skin on the bottom if you were worried about damage off road.
The other mod I would have made is a collection point internally at the outlet. The idea would be that it fills easily but traps some fuel there. So if your tank is getting low and you are breaking or cornering, the pump does not run out of fuel immediately. The factory tank does not have much fuel in the tank if you run it dry. This tank typically has 5L or more unused when empty unless you try and run the pump on hills etc to try and drain it fully.
This is an issue for me because I run two EFI pumps. The EFI pump (stock Bosch one) on the auxiliary tank runs the engine as well as transfers petrol, so I need to be aware of where I’m driving when I use the pump otherwise the engine runs out of fuel (and it’s not good for the EFI pump). this is not so much an issue with a transfer pump.
I set mine up this way for redundancy. If I ever have running issues and suspect the pump, I simply swap pumps and see if that helps. I also don’t need to carry a spare pump, as one is mounted permanently to the van.

Hi Jon.
Sorry for my late reply. I have not proceed with making them as I found a new old stock original trakka one, which was cheaper than making a new one 
I think Peter B. already put my designs up somewhere on the forum. I can try searching through my archives and post them again.
Cheers
Beau
No worries. I got hold of Peter’s file. Attached is an image of this for reference.
Thanks for the advice @cathrich1. I will try and add this into the design. All valid points.
