Help with Aeroquip fittings.

[phasemaster1]

Went to order my fittings from Aeroquip when looking up part numbers two listed a 37* and 45* flare. How do you know which is the one to use? Im using Russell -6 fittings for my efi filter and ls fuel rail fitting. Russell dosent list what degree flare they use. Im going with Aeroquip teflon lined hose. Thank you.
