I am in the process of replacing the hydraulic hoses on my Lancair360... I'd like to retain the fittings and simply disassemble the hoses, use new hose, and reassemble everything. My fittings all seem to be in fine shape and reusable.
I've got the BU-03 fittings and the Hytron HR303 hose. I can't seem to find the Hytron (now Dayco) hose and Lancair wants me to by all new fittings and hose... $$$  Are these  BU-03 fittings compatible with the Aeroquip 303 hose or am I better off getting all new fittings too? Are these BU03 fittings the same as an Aeroquip 491?

Thanks,
Andy Meyer
