Its a wonderful thing to see experimental aircraft actually being used experimentally like the FAA intended!!
My own choices of hose for my recent 5 year annual was Gate R7 stainless
braided hose for engine compartment, Gates R7 no braid aft of Firewall for
fuel. The R7 spec is the Fuel injection grade, replacing the low pressure
R5 hose with the original kit. The hose is also rated for longer service life.
For Oil hose I used the relatively new Aeroquip FC332 (blue) socketless
hose for oil lines. Coolant hose is also Gates.
All firesleeved.
Spring clips are or should be speced to the hose used. To see if CTC
is indicated in an application, one needs to check the specific hose
for the coefficients of expansion with heat and swelling with solvent
absorption. I suppose this is part of what they call "Rocket Science,"
Anyway, we are free (in the US anyway) to try different hoses and
report our results. So far, nothing to report in six months of service.
