What size is the fuel line on a Craftsman trimmer?
The Craftsman 13874544 is an electric line trimmer, so it does not use a fuel line. If you are trying to replace a “fuel line,” you likely have a different Craftsman gas trimmer model; use the 13874544 owner's manual to confirm what your unit uses and where the model tag is referenced.
What to check first (to make sure you have the right trimmer)
- Confirm the model number on the product label is 13874544.
- If you see a fuel tank, primer bulb, or carburetor, it is a gas trimmer (different model).
- If you see a power cord or battery pack connection and no tank, it is electric.
- Check whether you are actually replacing the trimmer line (cutting string), not a fuel hose.
If you meant “trimmer line” size (cutting string)
Many Craftsman electric trimmers use light-duty line, commonly in the 0.065 in to 0.080 in range. For the exact line diameter and spool style for model 13874544, follow the specifications and spool instructions in the 13874544 owner's manual.
| You’re replacing | Where it’s found | Typical “size” you’ll see |
|---|---|---|
| Fuel line (gas models only) | Between tank and carburetor | Inside diameter (ID) in inches or mm |
| Trimmer line (electric/gas) | On the spool in the trimmer head | Line diameter (for example 0.065 in) |
| Electrical cord/wiring | Handle, switch, strain relief | Wire gauge, not “fuel line” size |
Why it matters
Using the wrong line diameter can cause poor feeding, extra vibration, or motor strain. Confirming whether your trimmer is electric or gas also prevents ordering the wrong parts and chasing the wrong repair.
Helpful DIY tip for electrical issues
If the trimmer will not start and you suspect a cord or switch problem, a meter test is the fastest way to narrow it down; see how to use a multimeter to test electrical parts video.

Where to find model number on Craftsman Weedwacker?
On a Craftsman Weedwacker line trimmer like model 13874544, the model number is printed on the product identification label, usually on the motor housing, handle area, or near the guard where the shaft meets the head. We use that exact model number to match the correct parts and diagrams.
Common places to check on a Craftsman electric line trimmer
Look for a sticker or stamped plate that includes “MODEL” and sometimes “SERIAL.” Check these spots:
- Motor housing (side or underside of the main body)
- Rear handle or trigger handle area
- Shaft (upper section near the handle clamp)
- Near the cutting head/guard (where debris can rub labels off)
- Cord entry area (where the power cord enters the housing)
What the label usually looks like
Most Craftsman labels include a few fields. Here is what to capture before ordering parts:
| Label item | What to write down | Why it matters |
|---|---|---|
| Model number | Example: 13874544 | Ensures correct parts list and diagrams |
| Serial number | Letters and numbers | Helps identify production version |
| Electrical rating | Volts/amps | Useful for switch, cord, and motor troubleshooting |
Tips if the label is missing or unreadable
If the sticker is worn off, we still recommend narrowing it down using these identifiers:
- Compare the shape of the guard, shaft style, and handle design to the diagrams in the 13874544 owner's manual
- Check for any secondary numbers molded into the plastic housing (often not the model number, but helpful)
- Clean the area with a damp cloth first; grass residue can hide the print
Why it matters
Craftsman trimmers can look similar across multiple model numbers, but internal parts like the switch, cord set, spool housing, and motor components can differ. Using the exact model number prevents ordering the wrong replacement part.
