On a 1989 Mustang 5.0 fuel rail from the front...how can I tell which is the supply and return line?

Thank you for your help

They are different sizes, and the return line has the shrader valve in it.

Hi
I just checked and I dont see a shrader valve....where is it located? I see on the rail there is one line that gos to each injector is larger, but both lines coming to the engine seem to be the same size...is there another way to tell?

Thanks

Shrader valve is right in front of the passenger side head, right behind the alternator.

Are you positive the shrader valve is on the return?...wouldn't be on the high pressure supply side?

Sorry about that the shrader is on the FEED LINE, the larger line that goes into the front on the fuel rail, the return line is the smaller line that comes out in the middle of the rail.
