Fuel line replacement on Poulon 2050 14 inch Gas Chain Saw

Is there a special tool needed to reconnect the fuel line into the fuel tank & carburetor?

Any tips on reconnecting the lines is appreciated!

Thanks

    Thanks for the two quick replies!

    I thought the fuel line connected to a nub within the fuel tank and didn't pass thru it and the carb side also connected to the same nub but on the other side of the tank, otherwise I think it would leak fuel.

    Hope I am not sounding troublesome with my questions, just confused.

    Thanks again!

    The nub is designed as is the repair clamp for a garden hose meaning it has raised serrations that grip the hose.
    It takes a bit of force to push the hose onto the fitting which is a problem when you try to connect into the tank.

    Thanks again!

First rule is to replace only one line at a time. Needle nose pliers is the only tool you should need. Replace the fuel line from the filter in the tank to the carburetor by removing the filter from the line, extract the line out of the tank, and remove the other end from the carburetor. Use the old line to measure for the replacement. Measure the point where the old line passed through the tank wall down to the filter connection. Mark this point on the new line, and push the line into the tank far enough to attach the filter (which you have checked for plugging), then pull the line back out to the mark. Make sure that you use the proper line for this connection as the filter must flop around to the lowest tank level so that the saw doesn't run dry of fuel when operated on it's side. The other connections are straight forward--just replace one at a time. Don't be stingy in making looping turns as you don't want future kinks. Hope this helps!

    You should not have to push the pliers into the opening where the line runs. Try cutting the blunt end to a point so the point sticks through, then try to grab the pointed end and pull it into the tank interior side. Surgical 'hemostats' usually have a longer reach than pliers. If the line is over-sized, you may have problems with this procedure. Good luck!

    Do you see this 'nub' that you speak of? Most saws that I have run across, just pass the fuel line directly through the wall of the tank and rely on the line fitting tightly into the hole to block leakage. If you indeed have a 'nub', you can get long 'hemostats' from Harbor Freight tools to work inside the tank. I would think that the relatively long internal line plus the weight of the filter flopping around would work the line off of the nub. Any leakage is into the carburetor area and would be swept into the engine as it evaporates. Don't know if this helps any.

  • drallim May 03, 2010

    Any chance the nub unscrews or otherwise pops out? This makes you want to be very sure the lines are bad!

Fuel Line Replacement
  • The hose in the tank with the filter on the free end connects directly to the carburetor input connection.
  • If the saw is equipped with a primer bulb, the output line from the carburetor connects to the suction side of the primer (once the bulb is collapsed it draws fuel from the tank through the carburetor to refill the bulb as it inflates).
  • The pressure side of the primer returns displaced fuel to the tank as it is depressed.

After replacing the fuel lines on a mac3200 gas is running out of the bottom of the saw, after the tank emptys the fuel quits leaking. the saw runs great though


This is usually because you used a fuel line that is too small to seal the holes they pass through in the fuel tank. When they pass through the holes in the tank they should be very tight so gas cannot leak past the lines.

Poulon Wildthing 18" Gas Chain Saw


Some Poulans vent thru a fuel line going from the tank to the carburetor. Some vent thru the cap but eventually the duck bill valve starts leaking fuel. Then I suspect some people change that cap to one without a vent, which causes the problem you are describing.
