Hey guys, so i just did my injector install, but after I was done with it, I looked at the fuel lines and was curious as to which one was fuel feed and which one was fuel return....Some people are telling me that the line that is on top, the one that goes into the skinny rail, is the fuel feed, others are telling me fuel return, and then there's also the fuel line below this line, that connects directly to fuel rail, and some are telling me this is the fuel return and others, fuel feed. So what is it finally? thanks a lot!

 

make the fuel pump come on and see which one spits out fuel.

 

Or, somebody can just know lol....

 

The feed line goes into the fuel rail from the driver side of the rail. If you have the stock pressure regulator its on the passenger side and that is the return line.

 

Gottcha...yep, that's what a couple of my buddies told me and Adam from Devo just confirmed that too, and he really knows his stuff, so glad I got that squared away. thanks again
