REFLECTOR:Firewall penetrations (was Control Cables)

[KeithHallsten]

Wayne,
Yes, I agree that fuel lines passing through the firewall should make use of
bulkhead fittings.  I will also use bulkhead fittings if either of my oil
cooler lines pass directly through the firewall, rather than through the
duct openings.  However, we were talking about the oil cooler lines, control
cables, and instrument wires that will come out of the ducts.  I don't
really like the concept of the fairly large duct openings into the engine
compartment, so I'm leaning toward minimizing the number of various types of
lines that use that route, then closing the duct openings up as completely
as possible.
