Can anyone with an airflow performance fuel injection system installed on

the -10 tell me where they penetrated the firewall for the purge line. I'm

planning on installing a 45 deg bulkhead fitting in the same location

(opposite side) as the fitting for the fuel line and want to ensure there

are no interference issues with running the purge line from there. Also, if

anyone has a picture of the setup from the engine side that they could

forward, I'd appreciate it.



Thanks,

Just did this last week.  I ran a second 45 degree fitting below the

current fuel 45 fitting on the firewall.  Ran the line down the right

side of the tunnel, and put in a 90 degree bend into the left tank line.

I plan on Adel clamping the line to the right side wall of the tunnel

soon.  I also had to finagle a #4 line into a #6 line with some fitting

magic, but it was no big deal (the purge line is #4).

Beautiful layout.  With the selector on the right tank and the purged fuel

into the left line between the tank and the selector, you force the fuel

back into the tank without running a complete return line.  Why did you not

just use a "T" with flared ends instead of pipe threads and pipe-to-flare

fittings?



Do not archive?

Thanks Jesse - works exactly as you described.  Good point about the 

fitting, just a matter of mating together two sizes of tubing.  In the 

end I really just copied Dan Checkoway's installation: 

(http://www.rvproject.com/20030516.html). - Thanks Dan if you're listening!

Same reason I didn't - because the return line is #4 line and the fuel

tank lines are #6.... So you have to use an AN6 tee with a pipe end,

then a reducer to a AN4 fitting.   I have the exact same set up in my

-10, but I tapped into the left tank line instead of the right tank

line.
