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.
A typical fuel system
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.
The return line should direct fuel close to the bottom of the tank and away from the pickup.
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.
Product Details. Help protect your 2-Cycle gas outdoor power equipment with the Homelite 2-Cycle oil. This oil is a 50:1 gas-to-oil ratio. Use the whole bottle for up to 6 gallons of gas, or squeeze the bottle and let the top fill to a desired level.
The fuel line typically consists of rigid metal pipes, with flexible rubber or plastic hoses running from the pipes to the tank and the fuel pump , and from the pump to the carburettor . The flexibility of the hoses allows some movement between these different components.
Generally speaking, 3/8-inch fuel line is appropriate for most V-6, I-6, and V-8 engines and sometimes 5/16-inch will suffice for the smaller V-6s and I-6s. Likewise, you may want to go to 5/8 line and hose for a high-horsepower V-8.
Metal, Rubber, Braided, or PTFE
Fuel Lines can be made from many different materials. If you plan to race, be sure to check the rule book for your track or sanctioning body. Using the right material the first time will save you time, money, and headaches.

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.
Below is a drawing of how to route the fuel lines.

Homelite d3350b what is fuel oil mix i was told i could use 50 to 1 because the new oils are better?????
Buy a good quality oil and mix it to the OIL manufacturers recommendation regardless of what the chainsaw manual says. If you are poking around the barn and find an old can of Homelite 2 cycle oil that says mix 25:1 mix it at that ratio.
All modern oils, chainsaws, and the EPA recommend 50:1. There has been great improvement in 2 cycle technology over the years. To rich a mix causes carbon build up on the piston that breaks loose and scores the piston and cylinder, and it stinks!
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?
My Homelite Mighty Lite has developed perished fuel lines. (12 months after purchase!!!!!!) Is it possible to obtain spare fuel line…. preferably attached to a new fuel tank as well. It looks like a really hard task to change only the lines.
The fuel lines can be purchased separately usually by the foot from any outdoor power equipment dealer. They can be easily installed by cutting one end at an angle and “feeding” it through holes. Homelite fuel lines are of a different OD than most so make sure you get the proper size. The most popular size for Homelite is OD .203 ID .04.
Fuel Ratio Fuel mix ratio for Homelite (chainsaw) ut # 10520a
40:1 is about right. Be sure to use modern synthetic oils made for saws and premix thoroughly before adding to the saw.
Replaced fuel lines and pressing the primer pump does not feed gasoline to the car.
Sounds like you have the fuel lines switched around. The fuel line closest to the primer bulb will be the shortest line. It only goes 1″ or so into the tank. The other line will be the longest line, and sometimes the smallest in diameter of the two depending on the size of your trimmer, and must rest comfortably on the bottom of the tank.Jim
