Small Engines (Lawn Mowers, etc.): fuel & oil lines, oil lines, fuel tank

Question
I have a Mac 3216 chain saw and all the plastic
lines desingrated. I have the new primer and lines
but I can't be sure how to replace them. Do you
have a diagram? HELP

Answer
No diagram...sorry.  You have a 50/50 chance of hooking the lines up correctly the first time.

I usually remove the carb and inspect it also if the lines are rotted.  By examining the carb I can tell which line connects to the primer and carb.

The main nipple on the carburetor should connect to the line with the filter on it that runs into the fuel tank.

Let me know if this makes sense.
