I just purchased all the parts to comply with SB 25 from Aircraft Spruce I did not use Teflon hose I used Aeroquip 303 since you put firesleeve on it anyway why pay the extra money.
List of parts:
2 AN816-3D= $4.84
2 Aeroquip fittings 491-3= $19.60
2 ft 05-01842 AE102-8= $13.92
2 ft Aeroquip hose 303-3+ $10.40
Total=$48.70
For safety's sake you should order from CubCrafters one of there AN -3 fittings with the small hole in case the oil line ever breaks, that would mean you would only need 1 AN816-3D.
It takes about an hour to install the ends on the hose and the firesleeve.
