Worth a request for clarification (and/or request for regs change) before spending the money.

But you only have to seal the tubes if they go through the listed bulkhead between the passenger compartment and the trunk/cargo/fuel tank/fuel cell area; otherwise, you'd also have to seal the front door bars too. As you point out the section on door panel modification doesn't specify front or rear doors. Besides you must admit there's nothing wrong with a literal interpretation. IISYCYC.
