Fuel tank clearance (from boot)

[K3zBang]

G'day guys recently picked myself up a sub that weighs more then my car... It's a beast and was wonder how much room there is from the fuel tank to the boot?

I want to be able to screw it down nice and snugly but am scared of the tank, any help or advice would be awesome thanks guys.

It wouldnt be more then half a inch if that. I say if you had to do it, use 10mm self tappers. But then your still risking it.
