Hi, I'll try and help you. Can you tell me what the filter looks like? Is it sort of rectangular with one side being metal and there is one fitting on the top or cap and two on one side? If so, then it's actually a fuel pump. There should be arrows that will point to the in and out sides and the fitting on the top is for the impulse line which is the hose that goes to the block. Google Briggs part #692026 to verify what it looks like.
Let me know if that seems right. Thanks, PK.
The line from the block goes to the fitting that's on the cap of the pump or the half that only has one fitting. This is the impulse line and operates a diaphragm. It sounds like the way yours is put together is a little different with regard to the inlet and outlet fuel lines. All you have to do is hook up the fuel line from the tank to one of the other two fittings and crank the engine over. If the inlet and outlet fittings are both on the same side of the pump, then I believe it's the bottom one that's the inlet and the top the outlet.
This site may help you out.
Let me know if you have any trouble and if you can't get it to run you should consider that the pump may be bad. Thanks, PK.
