Per Greg - your really want to be sure that burning fuel cannot reach the passenger compartment. If you can seal the seems as best as possible you'll be safer and won't get grousing from tech. I have a bulkhead and was asked to run the metal duct tape all around any seam that might allow fuel into the passenger compartment. I appreciated the safety advice. They stopped short of asking me to put rubber seams where the bulkhead opened for fueling, but I was told in Prod or GT looks for that level of safety.
PS - I also have a very large bulkhead per the idea that much of the airspace is displaced in the cockpit creating a more aerodynamic car. I'm no car builder but thought I'd mention that as a possible performance advantage. Might make no difference. Makes for a very clean and professional look.
