Is this what you're talking about? There's a fuel barb sticking out on an angle that crosses the path of the main fuel inlet line and another pointing exactly the opposite direction on the other side of the accelerator enrichment pump. If I'm getting this right, the shop bypassed the accelerator pump and hooked the line straight up to the fuel return line - which is bad and stupid on the shops behalf.

Yeah that't it! I think I saw somewhere that, that is a return hose in that pic. But I think I remember something also being hooked up to that other port on the right in my pic. Does the fuel pump return go to that, then the return on the carb go to the tank? Dare I ask what the shop might have broken lol?
