At first glance when I got the 2000 ls1 from a trans am i saw two lines come from the top of the left valve cover and thought one was a supply line for the fuel and the other was the return line. but upon closer inspection i relised that the larger was the supply line and the smaller was the EVAP line for sucking fumes from the fuel tank or canister or something....is this right?

So my next question is since i only have one fuel line coming from the engine I'm guessing i will need a regulator with a return line going back to the tank because the pump I'm using says it will build a 100psi so what regulator should I get?

Yes you are correct. Most swaps are using the 2003 corvette fuel filter. it has a built in regulator. There is one in from the tank and one out to the fuel rail and another out for the return. or the more expensive method would be to do and after market regulator with AN lines.

Wix 33737, $32.79 at rockauto.com. You get a fuel filter and a pressure regulator all in one. Hard to beat that.

I'm just going to use parts store fuel injection hose (J30R9), the proper clamps, and Dorman parts store fittings to connect to my factory steel line. That's the cheap way, and it will be functional and look fine. I don't know what to buy if you want to get fancy.
