Have a 2010 4.8 from a truck. My question is the fuel rail being stock intake. What line is the supply and what one is the return line or how do you tell them apart. Thanks Nate

No it does not have a regulator. I purchased the LS kit from speedway with regulator. Was going to tie the return from the intake and the return from the regulator together back to fuel cell.

How would I tell if it does or not? I was told being a 2010 they didn't have a regulator on them. If so then would I not need to run a regulator and just go from pump to intake?

Thanks to the help from members. We figured out there is no return on this motor. The line in question with the green can is a emission line and not connected at all to the fuel rail. I will be plugging it off and using the corvette style regulator running the return on it to my fuel cell and the feed line to the intake. Thanks Again for all the help. It is awesome to have good resources when unsure.
