Default OEM Fuel Hardlines

I need to know what size the factory hard lines are that run from the fuel tank to the engine bay. Im trying to buy the correct size push lock fitting that works with the factory hard lines. Russell Performance has the following sizes...

-6 AN male to 1/4" SAE quick-disconnect female
-6 AN male to 3/8" SAE quick-disconnect female
-6 AN male to 5/16" SAE quick-disconnect female

Picture of fitting in question...

5/16" ~ 8mm

Got a caliper? You can just measure it to make sure!

I was under the impression they were 5/16" SAE; at least that's what the Aeromotive adapters to the stock lines are.

The question is what is the OEM line size. Subarus are made in Japan, they like metric overseas. I think only the big 3 here in the USA still use that crappy English unit system

for the fittings that will fit the 8mm OEM line: 5/16" = 0.3125" = 7.9375mm ~ 8mm
