Brian,
FWIW I have put it on the front of the seat bulkhead between the seats. The tube
is routed through a hole drilled in the port horizontal surface of the tunnel,
aft and inboard of the access hole for the rudder cable pulley. It goes
vertically
through a rigid plastic outer tube into a foam/bid "nose" bonded to the
top of the seat back, then across the top of the tank to a T connector in the
vent line.
Looks OK but be warned that I'm still a year or two of actually testing it by
flying.
Best regards,

Subject: Seatback sight tube
I know that a number of people are putting the sight tube on the seat back.
How do you deal with it getting crushed by luggage? I was thinking of a
plexiglass tube over the soft one.
How do you route the line? Presumably from the fuel fitting through the tunnel
and then through a drilled hole? How do you eliminate fretting? Where then
do you route the exaust tube? Under the upolstery but on top of the seat back?
I was also thinking of putting the sight tube on the seat back and all the way
to the filling side - this seems neater, and still easy to check when getting
in the pilot seat. This can't be checked when filling, though.
