Easy fuel pump question.  There are 3 ins/outlets on top of the fuel pump-I got those where they need to be.  There is a 4th connnection on the bottom towards the rear of the fuel pump-cant remember where it goes-cant find a loose hose.  Cant find it on the FSM drawings/Haynes manuals.  The tube comes out of the fuel pump, takes a 90 degree turn down towards the canister.
Would greatly appreciate the help, I have rebuilt my stock 1.3 1988 engine-had a hole in one piston-got almost everything back together but cant find this hose. 

Thanks to all.

Are you talking about the stock in-tank pump?  The mechanical pump? what?

The mechanical pump that bolts to the rear of the engine head, sorry for not giving enough details.  I am at a loss, searched the FSM, everything-nothing I have found shows that inlet/outlet.  It has been weeks since I took the engine apart to replace the pistons and rings-now I can not recall where that connection is/went.

Thanks so much for the help.  I am almost finished with my rebuild project.

that tube gets no hose.
i think it is a breather for the pump diaphram.
i know that if oil(or gas) comes out of it the pumps no good.
fire that baby up.
