Poulan 2050 chainsaw. Fuel line routing: Replaced all fuel lines which had rotted away. Primer bulb is marked tank and carb side. Tank side is for larger line and runs into tank. Is this the "vent line" that only sticks in about 1 "?. Carb side is smaller diameter line and runs to carb but which fitting? Remaining carb nipple with small line runs to tank and I guess the fuel filter? Cannot find specific info anywhere. I had the fuel filter on the larger line in the tank but that does not work as air is pushed OUT of filter that way. Thanks. Rick
