This was done at my local hobby store where they are able to vacuum canopies and r/c car bodies. This vacuum mould is strong enough to mould several tanks out and very easy to make. Sure you have can find such vacuum machine at a local hobby store??
Shock, I use a simple conventional gasoline rubber stopper (I think from Dubro...?) and glued a mating aluminium ring in the fuel cell with epoxy/microballoons, (Also used for the seam) look at the first thread I mentioned. Most people said the micro balloons wouldn´t work, will start leaking, but with two models in action for 5 years now all tanks are still leak proof with no signs of brown colorisation in the flanges
