EFI.. Need help now. which one is the return hose?

[Lonestar]

Hey guys, I am hooking up new fuel lines on my 92 Mustang HO 5.0 and I am not exactly sure which one is the return... Both look about the same with.

Is it the one with the Shrader valve?

The more detail the better

Thanks

If you are talking about the line on the fuel rail. The Fuel regulator will be on the return side. Remember that the fuel rails must be presurized and the way that happens is by the regulator being at the end of the rail. Hope this helps. I hooked mine up wrong the first time.

the regulator is pretty tough to see.. Does anyone know if the line with the shrader valve is the return or the feed??? ?
Thanks

the line with the shrader valve is the feed.
