Hi all urgently needed is a oka right hand fuel tank. New used or upgraded. Current fuel tank is rusting from the inside out and causing fuel blockages.
If any one has a solid non rusting tank available please call me 0488 365 286
Thanks
Chris

Chris, I used one off an Isuzu I think it was. I had to use the Isuzu mounts as I think that the OKA brackets may not of held it very well. The OKA mount was close to the end of the tank.

Are both tanks not the same? Just reversed in mounting north-south direction to allow access to the filler which is under an angle. The filler on the tank on the right is towards the rear, and when mounting this tank on the left it is next to the 2nd battery (if you have one that is).
I can't check physically as I sold the tank on the right.

unfortunately both tanks have the same problem. I am trying to get a price on a aluminum or stainless made up. Has anyone had one made up recently?

Have you considered use one of the fuel tank sealing products.

I had 2 aluminium tanks built, nearly ready for installation, see also this thread

I believe OKA parts also sells or can make new square tanks, bigger than XT/LT, more NT like. The above thread also shows some other ideas.

A tank sealer sounds interesting. Has anyone used it? What brand works best?
Thanks

When I was doing up old motorbikes 20-30 years ago, often the tanks were rusted and with pinhole-leaks. New tanks were expensive or not available, and welding.... stuff was far too thin (for me).

These were the steps I did, but there may be better methods:
1. Put some blue metal in it, shake it with some water, the longer and harder the better (to loosen any rust), and drain
2. and repeat that a few times
3. hose it out let it dry
4. rinse it out with acetone (mainly to take all the moisture out)
5. added advantage of the acetone was that every hole you would find: circle with texta
5. then cover the pinprick holes with ordinary blue-tac (on the outside)
6. use a long bolt full of tick grease and put that in place of the fuel-outlet
7. use 100 to 200 ml of very thin epoxy, and swirl that round until the epoxy started to harden (using mainly a rapid hardening epoxy)
8. repeat the above another time, ie after half an hour so one would still get a chemical bond as well
9. then do the same with a ticker epoxy (ie within half an hour), often once is enough, and let the majority sink/sag to the bottom where most of the rust and holes usually were
10. and a final coat of the thin epoxy again
11 remove the blue-tac, and grind out (carefully!!) and apply epoxy filler etc
12 remove the bolt and rinse the tank out several times
13. ready to paint!

I used the first few times epoxy stuff that was marketed for this purpose. Later I used marine epoxies, that I mixed myself. never had a problem of leaking again, or blocked fuelfilters/fueltaps for that matter.

Hmmm, shaking the fueltanks of an OKA? maybe rolling down hill? Put it on a thread-mill?
