简介

Almost all gas now contains up to 10% ethanol. Ethanol is one of the leading causes of damage to small gas engines. The alcohol can cause corrosion on rubber and plastic parts and can make gas powered yard tools almost impossible to start. I will illustrate how to replace the parts that are most common to fail,the primer bulb and fuel lines. While disassembled I will also illustrate how to replace the fuel filter and air filter of the Poulan P3314 2-Cycle Chainsaw.

    Terrific guidlines! I wasn't able to complete the work in 45 minutes - primarily because pulling the fuel lines through was a difficult task - but your detailed steps helped me make sense of the project. Thanks! - David Garrison

Hello, I noticed you might have gotten your fuel lines mixed up. Im not sure if it would make any difference in the operation of the chainsaw.

But during the disassembly stage, you have the thick fuel return line going from the purge bulb outlet port to the big hole towards the front of the fuel tank. Yet during the reassembly stage, you used this same hole for your fuel supply line instead.

The correct routing of the fuel lines is actually the way it was before you disassembled it.

Basically:

1: Thin line from right carburetor nipple gets routed through the small hole towards the rear of the fuel tank and is hooked up to the fuel filter inside.

2: Thick line goes from left carburetor nipple to the short nipple on the purge bulb.

3: And finally, another thick line goes from the long nipple of the purge bulb to the big hole towards the front of the fuel tank.

Great information here, I’ll use it to do the same job on my McCulloch 2214AV, it is almost identical to this Poulan.

:) very helpful!

very clear and well explained, I followed instructions and replaced both fuel lines. The fuel, heat and time just disintegrates these lines. Thanks
