Want to ask you gurus which options are there of securing a tank in the trunk area?

I bought a 2.7 gallon tank and I'm struggling to find a way to secure it without having to do some drilling? The only hole I would like to drill is for the pipe that supplies the methanol to the engine.

Any advice would be much appreciated!

 

I don't think you a choice here but to drill some holes. 2.7 gallon's is a big tank. What does it look like?
