Peter,
I found an almost new lynx fuel tank when I recovered the remains of 1726. It wasn't until I went to fit it I realized that I had two left tanks and no right. I soon converted a left to a right and this is the result.
It will give you and anyone looking at this thread, the style and shape of a Lynx fuel tank.
I also used POR15 tank sealer in both tanks just to be sure. I also had to modify the drain position in the fuel tank armour as well as the tank drain point was now in the wrong place for the original drain.
Regards Rick.
