Here are the guidelines I used for hoses and lines:

No aluminum tubing forward of the firewall.
No firesleeve aft of the firewall. Aluminum melts at ~1100 F, you are long
dead by then.
All flex hose forward of the firewall must be Stratoflex 124 with integral
firesleeve. (Sacramento Skyranch has a great deal here where they guarantee
the hose will fit or they will make you a new one even if you tell them the
wrong length).
NEVER use field replaceable fittings.
Always use swaged fittings and pressure test and flush before use.
Any hard line forward of the fire wall carrying fuel to the engine should be
300 series stainless steel and have firesleeve or other insulation to
prevent fuel vaporization. Firesleeve should be installed before swaging the
second end.

I used the factory provided hose and replaceable fittings to prototype and
then ordered proper hose assemblies from Skyranch. It would be impossible to
supply hose assemblies with the kit as they would never be the right length
for YOUR airplane.
