most fuel pumps work on demand nowadays, so yours may not have a return pipe ?
the k11 (CG) return pipe exits the fuel reg on the end of the rail, is yours the CR engine ?

I don't think the pump will run unless the engine is turning. and to be draining fuel while standing next to a running engine, is probably not good. I would just undo the pipe and siphon the fuel out.
