Source for Cherokee 6 fuel line fittings?

[Flying_Monkey]

Hi all, I'm looking to possibly replace the fuel line fittings where the tip tank connects to the fuel line near the fuselage. The fitting consists of a nut, union, and ferrule according to the parts manual. It can be visible by removing the flap track cover. The parts numbers are below along with the parts manual diagram. Just curious if anyone has a good source that might have these or if there are any replacement parts/numbers I can search for. Also if anyone has any experience replacing these I'd love to hear any insight. It appears like the connection may be slowly barely seeping and I'm thinking of getting ahead of it and replacing...Thanks!\\

31- 477680 NUT-(8B12-D)
28 - 491084 UNION-(8H12-D)
24 - 460463 FERRULE-(8T12-D)
