My Own Chainsaw Saga: A Lesson in Fuel Line Neglect

Before we get into the nitty-gritty, let me share a little story. I learned about chainsaw fuel systems the hard way. Years ago, I had a beautiful old Husqvarna (not a 455, but the lesson still applies). I’d used it hard cutting firewood for the winter. I was always diligent about sharpening the chain, but I completely neglected the fuel system. One spring, when I needed to clear some storm damage, the saw wouldn’t start. After much head-scratching and pulling, I discovered the fuel lines were cracked and brittle, and the primer bulb was rock hard. The ethanol in modern fuel had wreaked havoc. That experience taught me the importance of proper fuel system maintenance – a lesson I’m passing on to you today.

Understanding the Husqvarna 455 Fuel System

The fuel system on your Husqvarna 455 is relatively simple, but crucial. It consists of:

Fuel Tank: Holds the fuel mixture (typically a 50:1 ratio of gasoline to 2-cycle oil).
Fuel Filter: Located inside the fuel tank, it filters debris from the fuel before it enters the system.
Fuel Lines: Hoses that carry fuel from the tank to the carburetor.
Primer Bulb: A small bulb that, when pressed, draws fuel from the tank to the carburetor, making starting easier.
Carburetor: Mixes fuel and air for combustion.

When any of these components fail, your chainsaw won’t start or run properly. The primer bulb and fuel lines are particularly vulnerable to damage due to age, exposure to ethanol, and improper storage.

Identifying Primer Bulb and Fuel Line Problems

Here’s how to diagnose common issues:

Cracked or Leaking Primer Bulb: Visually inspect the bulb for cracks or leaks. If you see any, it needs to be replaced.
Hard or Stiff Primer Bulb: A primer bulb that feels hard and doesn’t compress easily is likely dried out and needs replacement.
Primer Bulb Not Drawing Fuel: Press the bulb repeatedly. If you don’t see fuel moving through the fuel lines, there’s a blockage or a leak in the system.
Cracked or Brittle Fuel Lines: Inspect the fuel lines for cracks, especially near the connections to the fuel tank and carburetor. Brittle lines indicate age and ethanol damage.
Fuel Leaks: Obvious fuel leaks around the fuel tank or carburetor often indicate damaged fuel lines.
Difficulty Starting: A chainsaw that is hard to start, especially after sitting for a while, may have fuel line or primer bulb issues. Air can enter the system, making it difficult to prime the carburetor.
Rough Idling or Stalling: Air leaks in the fuel lines can cause the engine to run erratically, resulting in rough idling or stalling.
Visual Inspection: Carefully check all fuel lines for signs of wear, cracks, or brittleness. Pay close attention to areas where the lines bend or connect to other components.

Tools and Materials You’ll Need

Before you start the repair, gather the necessary tools and materials:

New Primer Bulb: Make sure it’s the correct part for your Husqvarna 455 (OEM or a reputable aftermarket brand). I always recommend using OEM parts when possible, as they are designed to fit perfectly and perform optimally.
New Fuel Lines: Again, get the correct size and type for your 455. Measure the length of the old lines to ensure you get the right replacement.
Fuel Filter: It’s good practice to replace the fuel filter whenever you replace the fuel lines.
Small Screwdrivers: For removing and installing fuel lines and the primer bulb.
Pliers: For gripping and maneuvering fuel lines.
Pick or Hook Tool: Can be helpful for pulling fuel lines through tight spaces.
Fuel Line Installation Tool (Optional): This tool makes it easier to thread the fuel lines through the fuel tank. They are inexpensive and can save you a lot of frustration.
Clean Work Area: Work in a well-lit, clean area to avoid losing small parts.
Safety Glasses: Protect your eyes from fuel splashes.
Gloves: Protect your hands from fuel and grime.
Shop Rags: For cleaning up spills.
Fuel Stabilizer: Add fuel stabilizer to your fuel to prevent ethanol damage.
Camera or Phone: Take pictures as you disassemble the fuel system. This will help you remember how everything goes back together.
