Here is a schematic of the fuel system which might help you- listed as a 750 but identical to a 900:

No Darren, on the carb'd bikes the fuel filter is external and the pump is mounted to the frame, it's a Mikuni item often seen on snow mobiles apparently:
The three takes offs are: Fuel in, fuel out and vacuum to the vertical cylinder intake to work the diaphragm.

Also, it is easy to get the pipe connections the wrong way round on the pump if the pump has been messed with. Definitely worth making sure the tank air vent is clear by blowing it through from the fuel cap opening with an air line and making sure the flap valve in the petrol cap is not blocked or stuck shut. Both will cause fuel starvation eventually.

The very early 900's had their fuel filters mounted as you describe but I'm not sure if SD have got their photos quite right. All the '97ish 900's I have seen are mounted like this which they list as being for a 600/750 (although it is quite likely if ordered you would receive the correct part of course):
