So, my LS1 has a returnless fuel system... Two years ago, I installed my Procharger kit. The kit I bought was from an '01, soit came with an FMU (which I'd ditched a few months later for some injectors and tuning). In order to run the FMU, the return line from the engine to the gas tank is removed and the FMU takes it place. After removing the FMU, I just blocked the fuel port in the splitter block and hung my return line on the garage wall, where it's sat ever since.
Honestly, I've never had any noticeable problems. However, people look at me like I'm crazy when I tell them I run a returnless system, and especially that I did it by choice.
A friend of mine has offered to help me run the return line back into the car, which is fine. My question is, do I need to? What potential problems am I encountering by not running one?
You know, the usual. Thanks
