I inherited a mac 3216 chainsaw with no manual. The gas lines are rotted away of course primer bulb connects to the carb and other line goes tank but how does it end?

1. The fuel line from the tank to the carburetor should have a filter on the end of it. This filter helps to keep dirt and debris out of the carburetor, which can cause it to malfunction.

2. The fuel line should also have a small vent hole in the top of it. This vent hole allows air to enter the tank and helps to prevent a vacuum from forming, which can cause the fuel to stop flowing.

3. The fuel line should be routed in such a way that it does not come into contact with any hot parts of the engine. This is important because the fuel line can melt or catch fire if it comes into contact with a hot surface.

4. The fuel line should be replaced if it is cracked, brittle, or damaged in any way. A damaged fuel line can cause the saw to run poorly or even stop running altogether.
