While on the topic of things fuel related and my {soon to be} need to renew the tank on the Hyena, I recall some years ago someone was selling {remanufactured?} versions of the 80l tank originally available on the SA version of the T3.   

Does anyone know if such a thing is still available? 

Alternatively, a suitable aftermarket plastic tank would be preferable to another steel tank  … though the original has lasted 30yrs   (The original in my ’66 Westy is still fine … but a different location and set-up)
