Mark this length on the fuel line itself using a permanent marker or a piece of chalk. Make sure the mark is clear and visible, indicating the exact spot where the cut should be made.

Step 2: Identify the Cut Location: Locate the desired cut point on the fuel line. This could be where you want to install a new fitting or adjust the line's length. Use a marker to create a visible reference point. You can also use a piece of tape or a small piece of the fuel line material to temporarily mark the location, ensuring it stays in place while you work.

Step 3: Double-Check the Mark: Before making the cut, double-check the marked length and location. Verify that the measurement is correct and that the mark is in the right position. This step is essential to avoid cutting the wrong length or in the wrong place, which could lead to issues with the fuel line's functionality.

Step 4: Use a Marker for Precision: Markers are ideal for this task as they provide a clear and permanent indication of the cut line. You can use a fine-tipped permanent marker to draw a straight line along the fuel line, following the marked length. Alternatively, you can use a chalk line, which is especially useful for longer fuel lines, as it leaves a visible line that can be easily followed.

Step 5: Consider Safety and Accessibility: When marking, ensure that the fuel line is securely held in place to prevent any accidental movement. You might need an assistant to hold the line steady while you mark. Additionally, choose a well-lit area to ensure you can see the markings clearly and make precise adjustments if needed.

By following these steps and using markers effectively, you can accurately mark the cut length and location for your Duramax steel fuel line, ensuring a professional and successful installation or repair process.
