I'm going to be putting a piece of 3/4 in plywood down on the tunnel to help with the sound insulation. I'm going to use self tapping screws. Before I make any colossal mistakes what is the clearance under the tunnel? I know the fuel tank is under there and I don't want to puncture it.

I would plan carefully and conservatively. Measure twice and drill once. Maybe start with a very tiny hole and check clearance.

I measure three times. I have done some stupid stuff in my life.

Rather than self tapping screws, you might consider investing in a rivnut tool and some riv nuts for this. I've lost count of the number of riv nuts I've installed into my truck for mounting various equipment and such.
Makes it so you can easily remove and reinstall stuff without causing any additional damage like you might with self drilling screws, and also no sharp points sticking out underneath to possibly cause issues later.
