RV-4 pilot's foot well area

Hello,
RV-4 question:
I'd like some tips on how others have organized an area around pilot's foot well.
Page 39, section A-A' of the plans shows aluminum soft tube near the bulkhead.
Should that tube get covered, or just left "exposed" behind that bulkhead?
Thank you.

Mikhail

My first -4 had those lines per plans, exposed. No issues at all. My current plane does not have those lines. I coiled a few loops between the fuselage and the wing tank (like the rocket), thus far it is working well. I would do it again.
 
fuel vent area rv4

I know this is counter to Vans plans but the coiled vent works just fine and eliminates the aluminum tubing back in the cockpit. Works just fine in my 4 and in the rockets
Check out link listed below in Master Designs post. My link did not work.

Is that foil insulation on the back ofne firewall have plastic in the middle? If so that will melt and fill the cockpit with nasty smoke if you have a fire in the engine compartment. There is a thread on this somewhere. Sorry to be critical but it is a safety thing.
 
Look at the drawing again

Those vent lines should be tucked in behind that bulkhead/former, not sitting flat on the fuselage wall like you have it. It will fit. I secured mine with wdg clamps.
 
Thank you everyone for suggestions!
Today after work I made it out to the plane to have a look. It seems there is enough clearance between tubes and rudder cables, but I think I'll go with "coiled tube" idea.

I also cut off a piece of that aluminized insulation and set is on fire... sure enough, it released fumes. Should I completely remove it or use something instead?
Perhaps Thermo-Tec Adhesive Insulation.
 
I have no insulation on the inside of the fuselage at all. I do have on thin layer of foil insulation on firewall that I got from Flyboys.
