Q: How do I mix gas and oil? A: Mix 3.2 ounces of Poulan 2-cycle air cooled engine oil to one gallon of fresh unleaded gasoline to obtain the recommended 40:1 fuel to oil ratio.
A single fuel pipe runs from the tank, under the floor of the car to a mechanical pump on the engine. The pump delivers fuel to the carburettor. Whenever you check fuel pipes, disconnect the battery to prevent stray sparks igniting petrol or petrol vapour.
Most vehicles have rubber fuel hoses connecting the fuel pipes on the chassis to the fuel pump or carburetor on the engine. Rubber hoses are flexible and can be cut to length as required, but they have a tendency to perish over time and can rub through if not properly secured.
Fuel Pumps & Lines
Located in the fuel tank, your fuel pump moves gas from the gasoline tank to the engine. The pump creates the pressure needed to move gas from the fuel lines to the engine. While your car is running, the fuel pump is in constant motion moving fuel until your vehicle starts to run low on gas.
For a 50:1 ratio of gas to oil, use 2.6 fluid ounces of oil per gallon of gas. For a 40:1 mixture, use 3.2 fluid ounces of oil per gallon of gas.
One is the high pressure line, which sends fuel to the injectors. The other is the return line, which dumps fuel that the injectors don`t use back into the tank.
The (clear) fuel intake line runs from the top of the carburetor (straight nipple) and goes to the short post on the back of the primer bulb. The return line (blue) comes from the long post on the back of the primer bulb and goes into the bottom of the fuel tank.

Replaceing fuel line in polan 3300 chain saw – Poulan Pro 42CC 2 Cycle Chainsaw, 18"
Use a piece of wire and insert it into the fuel line, then bend a hook in the end and hook it over the end of the fuel line…lubricate the fuel line with some vaseoline very lightly…about the first one inch of the fuel line and then use your fingers to start the fuel line into the tank, once you have the fuel line in the tank give enough to hook the fuel filter to and so it can be dropped back into the tank.

The saw starts up fine, runs fine but not for long. it runs for about 1 minute and dies. like it is out of fuel or sucking air, i noticed there is no filter on the suction line and there is another nipple entering the fuel tank which appears to need a hose on it , is this just a return line, or should the long line in side the tank press on to this nipple? thanks,
I’ve had my pp4218 for about 2 years and the fuel lines have rotted. I’m thinging from ethanol in the gas. However, I’m replacing them and cannot tell which lines go where. Does the large line from the bubble go to the filter and the little line return?
Poulan chainsaw 18″ 42 cc, pro gas filler cap?
Yep they swell after a while and will not screw in or out!
Sand the threads down so that the circumference is reduced with a course file or plumbers cloth, chamfer the threads a bit on the edges. A new one will do the same thing after a while so just fix the one you have.
How do i gey new fuel line through case and into tank?
Is there a metal fitting on the tank top that will unscrew? If so, pull the old line out with the fitting (remove the filter first). Be sure to use original type line, not plastic which is not flexible enough. Hope this helps!
