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.
