Im well under way into putting a 5.3 with all the ls1 goodies into my v6 camaro, my question now comes to fueling, I have the ls1 intake, injectors, and rail. But the v6 camaro leaves me with 3 fuel lines, and the ls motor with 1 inlet. I have heard of the ls conversion guys using the corvette filter up front so they dont have to move anything, this is my plan but how do I know which of the lines is supply and which is return, short of turning the pump on and standing back....

Also, what do I do with the evap line? Im not at all familiar with EVAP, I have no idea what it does or what to do with this hose.

No one knows what the evap is or what to do with it?

I'll give it a shot! Very simply, the charcoal canister at the fuel tank collects vapors from the tank and when the computer feels it's time to dump these vapors (based on fuel tank pressure-maybe other inputs?) it opens the evap purge valve and dumps them into the intake at the throttle body. I don't believe it hurts performance. You can remove it completely from the vehicle but you may have to use some kind of fuel tank vent or vented cap. I'm leaving it in my LS1 powered Rambler because people on this forum suggest that this system may help to eliminate gas smell in a garaged car.

The feed and return are different sizes and only fit on the right fitting. Feed is the bigger one and return is the smaller one. Another route is to use the 97 Vette fuel rail which has the regulator on the rail. The evap line is hooked to the solinoid on the intake near the driver side fuel rail.

I used the Vetter Filter/Regulator, there is a pic of it in my Swap Thread.

Does anyone know where each of these lines go to?
