I got creative with my fuel line rounting to leave some space under the valve to run the scat tube.  See the picture here:

 http://kochman.net/N819K/wp-content/uploads/2009/03/img_5098.jpg

  

 My intent is to run the scat tube by the valve under the valve and rudder cable on the right side (left when looking at the picture).  I will likely wrap the scat tube in the heat reflective material to minimize heat around the fuel lines.  Note: the fuel line from the valve to filter is not shown in the picture, but goes straight down and thus should not interfere. 

 Anyone see a problem with this?  Thanks...

Looks like you’ve got more room than I do, I planned to make a fiberglass plenum going from one 2” scat to two 1” scat, then another plenum back into 2” on the aft side of the spar…for sure it would be more work, but I wasn’t smart enough to turn one of the Andair fittings 90 degrees…mine are both vertical so I have less room to work with unless I go back in and totally replumb.

That might be what I end up doing Deems...it looks like it'll work.  I've

got some upcoming spinal surgery in April...so a little fiberglass project

might just keep my head in the game...



I was thinking more of a one tube to two tube contraption...the idea being

to maintain airflow volume, but still minimize the scat size (sounds like a

wildcat hunting expedition...)...I'll let you fly a little in cold weather

and let me know how much heat you get in the back before I move forward with

my little fiberglass project, that means (you'll have to get those 40 hrs

flown off and) come up here to Oregon this month!!!  



I'll buy you and Ed Hayden lunch here in Independence and show you our -10

project...and of course, (it goes without saying here in Independence, 7S5);

you've always got a free place to stay, a car (and/or bicycle or motorcycle)

to drive, and we can find you a hangar for the night.



THANKS for the photolinks.  That's exactly what I was looking for...visual

ideas.

Just a quibble: two 1" lines will not "maintain the flow volume" of one 2" line, since the cross sectional area varies as the square of the diameter (e.g., two 1" lines provide half the cross sectional area as a single 2" line).

And a good quibble it is...I know that, but my point was that going from one

2" line to a single 1" line may not provide enough heat...I was just trying

to "fit between" the pieces I have and that's why I proposed the idea.  I

haven't started doing anything on it, still scratching my head...



Thanks for the clarity and observation!

When I open some of these posts...I get nothing but a blank page.  What's

up?
