There are two fuel lines on a Poulan 2050 Wild Thing chainsaw: a fuel supply line and a fuel return line. The fuel supply line is the line that carries fuel from the fuel tank to the carburetor. The fuel return line is the line that carries excess fuel back to the tank.
Step 2: Trace fuel supply line.
The fuel supply line starts at the fuel tank. It then goes through the fuel filter, which is located on the side of the carburetor. The line then connects to the carburetor at the inlet port.
Step 3: Trace fuel return line.
The fuel return line starts at the carburetor at the outlet port. It then goes through the fuel filter before returning to the fuel tank.
