Modify the tank compartment such that the tank can be removed.
Are you sure you need to do this?
I used a Du-Bro tank in mine (I don't remember the size but it was the one shown on the plan). After installing the wing tube I realised I couldn't put the tank in place. However after some thinking I realised that by mounting the tank upside down it would slip in place very nicely with no need to modify the tank compartment whatsoever.
You may want to try this before modifying anyting.
