I can’t figure this one out. I found some fuel line adapters summit has that would allow me to use my stock fuel rails and run stainless lines to the factory metal lines (bypassing the brittle plastic lines GM uses).
3/8 for the feed line

5/16 for the return

but what the hell does a 10mm fitting connect to? I’ve gotta be missing something somewhere
the fuel line on stock is prob 10mm and it adapts to 3/8 so you can make AN lines then
X2.
I pretty sure most of the GM stuff with the plastic fuel lines is metric line.
so 3/8 is -6 right? does it need any other adapters or can I bolt on a -6 hose end
