Hello Christian,

I have never been a fan of helicoils. A much better solution is the timesert. You can read up about them here http://www.timesert.com/  If you get everything clean and use these you will be up and running again at a fraction of the cost of a new tank. As these units require a slightly larger hole than the helicoil, you will be able to save your tank. Their kits come complete with the correct drill and installation tools. You will have to remove the tank to do this properly so add a manifold gasket to your parts order.   

The timesert kit that you want is their part # 18100. Their website shows 3 different distributors in Australia.

There is a Beta Marine distributor in Australia so I suggest that you contact him for any parts. His email is gktownsend@bigpond.com 

We supply engines and parts within the USA and to our customers when they are cruising.

Have fun, Stanley
