You're right but the pipe it's connected to isn't the flow pipe into the pump - as suggested by @Hugh Jaleak , the bypass pipe from...

Looks to me like it's going into what was the Cylinder Primary return.

It is yes ... but that's not the negative side of the pump - the positive side of the pump is out of the top upwards towards the 3 port...
