Budget friendly Return Fuel Line Hose&Fittings?

Was not leaking at all until I removed them to perform a leak-back test.
Now hose around #2,#3 and #4 are wet. I'd rather change them than zip tie/look for matching O-rings.

Metal fittings instead of plastic, but $97

Maybe complaining about the price of parts on this forum is discouraged (it is a pointless type of complaint), but we're talking about 1.5ft of hose and some plastic T's. Does anyone know of a cheaper source? Can these be made from other material?

Rock auto has some inexpensive items under this category, but I'm not seeing any descriptions for any of those part numbers online, just schematics and they don't point to a section of hose, or any T fittings.

Youtuber RUVA replaces his return line fittings, shows bags with a lot of extra hose, maybe there's a place to get this?
