Nice work, Mike.  I'm across the way in Melbourne.

Do you have any concerns with the fuel rail plumbing?  My EAA tech
counselor (and other sources) insists on using AN plumbing with fire
sleeved lines, especially on high-pressure EFI systems.  There are also
a lot of cases of the Mazda fuel rail pulse dampener failing in cars and
spraying gas all over the engine.

Cessna recommends SS tubing for its high-pressure lines whenever a rigid
line is used.  I'm using .035 SS 3/8" tubing and steel fittings for my
high-pressure (rigid) lines, and a racing source pulse dampener.

Mike,
Thanks for posting the pics.  I was wondering where I was going to put
all of this stuff.
