03 Should Be Return
2 Fuel Lines= Return
1 Fuel Line = Returnless

It is easy to tell, like said, one fuel rail on the driver side will have 1 line, pipe going to it,returnless. The return one will have 2 lines going to the rails on the drivers side..

Here is mine best I got. Return system see the two lines going to the rail. (Don't worry I changed them springs out )
