98 425 magnum fuel pump diagram

I just bought a 98 425 magnum 4x4 and was wanting to know if someone had or knew were each of the lines that come off the fuel pump are to be connected in order for it to work theres 1 line on the top of the fuel pump and 2 on the bottom side but not sure which ones are to go to the carb for suction and which one is to go to the tank it's self and the schematics I am pulling up for the parts list isnt showing me what I am needing to see

The one on top goes to the right side of carb (by your right leg) This is vacuum. The 2 lines on the side of pump should have arrows for in / out

yes if your looking at the pump mounted on the top the very top line is the pulse line the one directly below it is the line to the carb and the one closest to the front of the quad goes to the fuel tank your pulse line runs to the right side of the carb and the fuel line runs to the left side as you are setting on the quad

I just want to clarify, because I think I found the problem with my quad.

The fuel supply line that goes in to the carb is located on the lower side of the carb, and feeds in to the bowl where the float is located. The pulse line goes into the upper side of the carb on the right hand side? Please let me know if I am understanding this correctly.
