I have a Briggs and Stratton 21 hp engine model 331877 type 1449 G1 and removed the two hoses from the fuel pump to remove the engine shroud. One is from the fuel tank and the other is from the crankcase which I assume is to actuate a diaphragm in the pump. I didn't pay attention to which went where. The hose that is connected goes to the carb. Any ideas?

The one with "P" is the impulse port and the other is the fuel tank line in port.

Well I'll be darned, I didn't see the P. Thank you.
