    If replacing an old Cessna hard line oil pressure line with Stratoflex 193-2, with 311-2D fittings does this produce a direct replacement... or does any of the AN hardware need to change? In other words, are the 311-2D shaped to fit the same male flare fittings that the hard line did?

    BTW, same as Aeroquip 471-2D if that is more familiar.

    Should all be the same 37* flare fittings. Just, uh, make sure you do a good leak check on the ground before you go fly.

    Thanks Roger, that's what I was thinking but wasn't quite sure.

    Anybody have a trick for installing the #2 471 fitting? I know you can use a mandrel on the larger fittings but there is no mandrel available for the tiny #2... not sure how to get the inner threaded fitting inserted into the tubing, need something to push and turn on the inner fitting to thread it into the tubing.... seems like it should be easy but something isn't adding up.

    In case someone comes across this in a search: just buy a spare male fitting, screw it into the flare end of the 471 hose fitting and use that to push/thread the inner piece.... works just fine.
