Craftsman Chainsaw 358 Fuel Line Guide: Expert Tips for Repair and Replacement
The Craftsman 358 chainsaw, known for its affordability and ease of use, is a popular choice. However, like all small engines, the fuel line is susceptible to wear and tear. Ethanol-blended fuels, common today, can degrade rubber and plastic fuel lines, leading to cracks, leaks, and ultimately, a chainsaw that won’t start or runs poorly. I’ve personally seen countless saws sidelined by this issue, and a little preventative maintenance can save you a lot of headaches. This guide will provide you with the knowledge and skills to tackle fuel line issues on your Craftsman 358 chainsaw.
Understanding the Fuel System: Key Concepts
Before diving into the repair process, let’s define some key terms and concepts:
- Fuel Line: The flexible tubing that carries fuel from the fuel tank to the carburetor.
- Fuel Filter: A small filter, usually located inside the fuel tank, that prevents debris from entering the fuel line and carburetor.
- Carburetor: The engine component that mixes fuel and air to create a combustible mixture.
- Primer Bulb: A small, clear bulb that you press to draw fuel from the tank to the carburetor, making starting easier.
- Fuel Tank Vent: A small valve that allows air to enter the fuel tank, preventing a vacuum from forming as fuel is used.
Green Wood vs. Seasoned Wood: While not directly related to the fuel line, understanding the difference between green and seasoned wood is essential for chainsaw use. Green wood is freshly cut and contains a high moisture content (often above 50%). It’s heavier and harder to cut. Seasoned wood has been allowed to dry, reducing its moisture content (ideally to 20% or less). It’s lighter, easier to cut, and burns more efficiently in a fireplace or wood stove. I’ve found that using a sharp chain, maintained with proper filing techniques, is crucial for efficiently cutting both green and seasoned wood. This is especially true for harder woods like oak or maple.
Diagnosing Fuel Line Problems: Is it Really the Fuel Line?
Before replacing the fuel line, it’s crucial to confirm that it’s actually the problem. Here are some common symptoms and diagnostic steps:
- Chainsaw won’t start: This is the most common symptom.
- Chainsaw starts but dies quickly: This suggests a fuel supply issue.
- Visible fuel leaks: Obvious cracks or leaks in the fuel line are a clear indicator.
- Hard starting: Difficulty getting the chainsaw to start, even after priming.
- Rough idling: The engine runs unevenly or stalls at idle.
Diagnostic Steps:
- Visual Inspection: Carefully inspect the fuel line for cracks, kinks, or leaks. Pay close attention to the areas where the fuel line connects to the fuel tank, fuel filter, and carburetor.
- Primer Bulb Check: Press the primer bulb several times. If it doesn’t fill with fuel or if you see air bubbles, it indicates a fuel supply problem, possibly a cracked fuel line or a clogged fuel filter.
- Fuel Filter Inspection: Remove the fuel filter from the fuel tank and inspect it for clogs or damage. A dirty fuel filter can restrict fuel flow. I once spent an hour troubleshooting a chainsaw that wouldn’t start, only to discover a completely clogged fuel filter! A quick replacement solved the problem.
- Carburetor Adjustment: While not directly related to the fuel line, an improperly adjusted carburetor can also cause starting and running problems. Consult your Craftsman 358 manual for carburetor adjustment instructions.
Tools and Materials You’ll Need
Before starting the repair, gather the necessary tools and materials:
- New Fuel Line: Purchase a fuel line specifically designed for your Craftsman 358 chainsaw. Measure the old fuel line to ensure you get the correct diameter and length. I recommend using high-quality fuel line that is resistant to ethanol.

Expert Tip: When installing the fuel line, pay attention to the routing. Make sure the fuel line is not kinked or pinched, as this can restrict fuel flow. I’ve found that using a small amount of silicone grease on the ends of the fuel line can make it easier to install.
Common Problems and Solutions
- Fuel line is too short: Ensure you purchase the correct length of fuel line. It’s better to have a slightly longer fuel line than one that is too short. You can always trim it to the correct length.
- Fuel line is difficult to install: Use the small hooked wire or wire coat hanger to guide the fuel line through the fuel tank opening.
- Fuel line leaks: Ensure the fuel line is securely attached to the fuel tank and the carburetor. You may need to use small hose clamps to secure the fuel line.
- Chainsaw still won’t start: Double-check all your connections and ensure the fuel filter is clean. You may also need to adjust the carburetor.
Fuel Line Material and Ethanol Resistance
As I mentioned earlier, ethanol-blended fuels can degrade rubber and plastic fuel lines. When purchasing a new fuel line, look for fuel lines that are specifically designed to be ethanol-resistant. These fuel lines are typically made from Viton or Tygon, which are more resistant to the corrosive effects of ethanol. I always recommend using ethanol-free fuel whenever possible, especially for older chainsaws.

Case Study: Reviving a Neglected Craftsman 358
I once acquired a Craftsman 358 chainsaw from a friend who had left it sitting in his shed for several years. The chainsaw wouldn’t start, and the fuel lines were cracked and brittle. After replacing the fuel lines, fuel filter, and spark plug, and cleaning the carburetor, I was able to get the chainsaw running again. This experience reinforced the importance of regular maintenance and proper storage. The chainsaw, though neglected, was ultimately salvageable with a few simple repairs.
Understanding Wood Types for Firewood Preparation
While repairing the fuel line gets your saw running, understanding the wood you’re cutting is crucial for efficient firewood preparation. Different wood types have varying densities, moisture content, and burning characteristics.
- Hardwoods vs. Softwoods: Hardwoods (like oak, maple, and ash) are generally denser and burn longer than softwoods (like pine, fir, and spruce). Hardwoods also produce more heat.
- Wood Density: Denser woods require more energy to split and cut. I’ve found that using a hydraulic log splitter is essential for efficiently processing hardwoods like oak.
- Moisture Content: As mentioned earlier, seasoned wood burns more efficiently than green wood. Aim for a moisture content of 20% or less for optimal burning. You can use a moisture meter to check the moisture content of your firewood.
Example: Oak, a dense hardwood, takes longer to season (typically 1-2 years) but provides excellent heat output. Pine, a softwood, seasons more quickly (6-12 months) but burns faster and produces less heat.
Splitting Firewood: Techniques and Tools
Once you’ve felled and bucked your trees, the next step is splitting the wood into manageable pieces for firewood.
- Manual Splitting: Using an axe or maul is a traditional method of splitting firewood. It requires significant physical effort and skill.
- Hydraulic Log Splitters: Hydraulic log splitters use hydraulic power to split logs. They are much more efficient than manual splitting, especially for large or dense logs. I personally use a 25-ton hydraulic log splitter, which allows me to split even the toughest oak logs with ease.
- Splitting Wedge: A splitting wedge can be used to split particularly difficult logs. Drive the wedge into the log with a sledgehammer.
Safety Tip: Always wear safety glasses and gloves when splitting firewood. Maintain a safe distance from the splitting area.
Stacking Firewood: Best Practices
Properly stacking firewood is essential for allowing it to season properly.
- Elevate the Firewood: Stack the firewood on pallets or other materials to keep it off the ground. This will improve airflow and prevent moisture from wicking up into the wood.
- Stack in Rows: Stack the firewood in rows, leaving space between the rows for airflow.
- Cover the Top: Cover the top of the firewood stack with a tarp to protect it from rain and snow. However, leave the sides open to allow for airflow.
- Choose a Sunny Location: Stack the firewood in a sunny location to promote drying.
Case Study: Optimal Firewood Stacking
I once conducted an experiment to compare the drying rates of firewood stacked in different configurations. I stacked oak firewood in three different ways:
- Traditional Stack: Firewood stacked directly on the ground, tightly packed.
- Elevated Stack: Firewood stacked on pallets, with space between the rows.
- Elevated and Covered Stack: Firewood stacked on pallets, with space between the rows, and covered with a tarp.
After one year, the moisture content of the firewood in the elevated and covered stack was significantly lower than the moisture content of the firewood in the other two stacks. This demonstrates the importance of elevating and covering firewood for optimal drying.
