I have no idea where all you guys are meandering around, but you need to look for CPC connectors, which is the generic name.
The OEM plastic female ones are fine. It’s the plastic male connector which usually fails. So at the very least you can either replace just the male one with another plastic one and keep it well greased as Steptoe suggests, or just replace the plastic male with a metal one. Preferably brass or brass plated. But make sure the item you buy either a male, or a female has a built in check valve which will shut off the line once disconnected.
If your looking at Tom Parker connectors then here you go, but they are pricey.
8mm for the standard fuel connections, and 6mm for the Adventure cross over pipe.
Shop around.
