1973 50ESL73R Fuel Pump Help!!

[66Niagara]

Ok so I have an issue. The guy i bought the boat from had a universal fuel pump put on it. NOT SUPPOSED TO BE THERE! however I want to replace it with the one thats actually supposed to be there. I don't have any diagram or anything showing what hose goes where and the hoses that are connected now are not right. If someone could give me pictures of where the hoses go from the fuel pump to the carbs and etc it would be much appreciated!! HELP!!

Fuel from the tank goes to the filter cap.---------Put the filter cap on the pump and blow into that barb.----- The one that you get air out of goes to the carburetor.-------The other goes to the crankcase.

Thank you! I do have one question for you. There is 3 places to put hoses there is one on the bottom carb one on the top where I see on the diagram that its supposed to be one hose attaching them together. then there is one in the middle of those two carbs that whoever put this pump in stuck a bolt in the end of that hose. so that would be where I would put this hose from the one I get air out of to? and then the other one goes to the crankcase but where theres not even one going to the crank case right now from what I see. Also there is a nipple on the bottom of the air silencer base. what is that nipple for? What does it do and where is the hose supposed to go from that nipple? I figure it was for excess fuel but where is the other side of the hose from that nipple supposed to attach to. here is some not so great pictures of it.
