Outstanding twists and turns in this thread! (Pun intended
)
But seriously I will be in touch when we get ready to replace our hydraulic lines on the B17.
If the means exist to keep the systems with original style and color fittings without it breaking the bank I would love to do it.
My Army helocopter mechanic always calls the Blue fittings pneu-draulic because he was taught that they were suitable for either pneumatic or hydraulic applications.
An ex-Lockheed C-130 wrench has been insisting that if the fittings aren't blue they won't do!
There seems to be no lack of opinions in this whacky warbird community.
