I am sitting around waiting for my wing kit to show up (ordered last November) and decided to start researching hoses for the firewall forward. I could use some help understanding the differences in hose types, fluid compatibility, and fittings.
So far I understand aeroquip and stratoflex are generally available in stainless steel braided hoses and they would be capped with aluminum or SS fittings. Aeroquip 601/701 seems to be the standard with a synthetic rubber core and SS overbraid. However TS Flightlines seems to use Teflon core with SS overbraid. I am currently assuming it is Aeroquip 666 hose. Teflon appears to handle any fluid while the synthetic rubber can't handle hydraulic fluid. So this leads me to believe I should just use Teflon core Aeroquip 666 hose for all flexible fuel, oil, and brake lines. I am still working on which fittings to use with the idea that aluminum are fine behind the firewall while SS should be used firewall forward.
I am also reading that the 5052 aluminum is generally preferred over the softer 3003 aluminum that comes in the kit for the rigid lines, although tougher to work with.
Please correct me if I have stuff wrong, but what I could use some help understanding is the following questions:
What type of hose (core type or brand) is generally in use for the fuel lines, oil lines, and brake lines?
What sizes are these hoses (-4, -6, -8, or ID and OD if known)?
What type of fittings are being used for the respective hoses (aluminum, SS, Brand, etc.)?
I can completely understand why so many people simply pay TS flightlines to send them their hoses pre-fabricated, but I am trying to fully embrace the experimental mindset of learning new skills, understanding what I don't currently know, and building the airplane to the maximum extent possibly myself. Thanks for any light you can shed on the subject.
