The new fillers I am installing have a vent/breather connection as well, and was wondering to connect the vent of the new tanks to this or use the existing vent system. But by the looks of it it easier to use the existing breather lines. And it is high enough.
Hmmm, if the water is coming over the engine it it time to change the OKA for a boat anyway.....

Hank, note the breather connection to the tanks is a non-return valve, so excess air pressure can escape but stuff (like very high water levels) can't drain or be sucked back into the tank. So your air drying filters can't work in the breather lines and a fuel outlet water separator would be required.
Axle/transmission breathers don't have a non-return function.

In my case, I removed the existing tank and the non-return valve was fitted on that, according to the drawing. My new tank does not have a non-return valve; well, I never planned for that. Hehe, another case of ignorance?

The diagram of the actual fuel tank shows a normal fitting, only the breather diagram show it as a non-return fitting, so maybe you don't have them anyway.

Have had new 160 litre aluminium square tank made for drivers side of #149.
same height and length as original but wider
i am modifying original support brackets today
Tank is 3mm
Should I put bash plate underneath?
If so what material and what guage?
problem is, plate would sit very close to bottom of the tank, separared only by support rubbers.
Gap will fill up with muck

Estimated capacity?
You need some NOS stickers and chrome hoses to match now

High density polyethylene (HDPE).
Buy a sheet from your local plastics supplier or fabricator. Any thickness you want, but 4mm would be plenty.
Can be hot air welded or heat and bend. It is also possible to cold bend it if you have some mechanical 'help'.
All the mudguards (from top to bottom of the 'flaps') on #196 are HDPE and the rears are 10 years old. Bullet proof.
Cheers, Peter.

Your tank looks brilliant. Do you mind me asking how much it cost?
Cheers,
Paul

Tank was built exactly to my drawing by small long established local company Reid's Engineering who have a reputation for high quality esp with aluminium.
Cost depends on how much work they have.
..Don't know if they could charge the same second time round, mine was around the $900 mark.
This did not include cost of the cap and neck which I supplied (bought a matching lockable pair from Hiltons),along wirh the sender and fittings from my old tank.
Best thing is they build to your specs

I have made rears from roto-moulded HDPE plastic, but they are inside the chassis rails.
I am thinking about making some plastic ones to replace the OEM ones but they are outside the chassis rails and the rules may vary because of that?
Does anyone know?
Cheers, Peter.

The photo is from AMH website and the wording from the photo: "This photo shows the 160 L auxiliary fuel tank, the 40 L waste water tank low down, and the front-top of the water tank between the frame members. The centre "kinetic" suspension mounting is also visible, immediately to the rear of the fuel tank."

I wonder what - if anything - 'Kinetic Suspension' means? Is it just rubbers as in the Oka, or is it really something special?
