I bought a new vacuum pump for the Benelli 491. Because the scooter on the tank has two gas exits, I decided that I need a pump with four connections. I bought a pump with 4 connections, but I'm not sure if it's right. It has exits in, out, vent and bottom vacuum connection. there is no mark on my exits on my old pump, I am wondering whether I can connect one exit from the tank to the in and one to the vent, out and the vacuum go to the carburettor?

Never say never but... I've worked with quite a few fuel pumps. I've never seen one with a nipple for a vent. From the shape I think you have the pulse connection right(vacuum input). The other three could be any combination. Usually you have one fuel input and anywhere from one to multiple fuel outputs. Doesn't the pump body have any sort of nipple labeling or arrows?
