Small Engines (Lawn Mowers, etc.): Poulan 2450 chainsaw, small screws, tank wall

Question
replacing rotten fuel lines, saw used very little. Does the large line go from bulb thru tank wall to filter? Does small line right side of carb just go thru tank wall & stop or does the little barbed connector go on the end of it. Thanks Roger

Answer
The carb itself has two covers on it, one cover is held on with one
large screw, the other cover, 2 or 4 small screws.
The nipple closest to the cover with one screw is the one going to
the weighted fuel filter, and should be long enough to go to the bottom no matter what position the saw is held.
   The primer moves fuel only one direction, and it pulls fuel
from the other nipple and returns it to the tank.  The little barbed connector does not have to be reused, as long as the lines are routed correctly and don't leak.
