Cut and Remove: Carefully cut the damaged line and remove the old filter

When dealing with a broken fuel line that has damaged the filter, the first step is to ensure you have the necessary tools and safety equipment. This includes a fuel line cutting tool or a sharp, clean pair of scissors or a utility knife, gloves to protect your hands, and safety goggles to shield your eyes from any potential fuel splashes. It's crucial to work in a well-ventilated area or outdoors to minimize the risk of inhaling fuel fumes.

Locate the damaged section of the fuel line. This area will be characterized by a break or a significant reduction in the line's diameter, often accompanied by a visible leak. Carefully inspect the surrounding area to ensure there are no other issues or potential sources of further damage.

Once the damaged section is identified, carefully cut the fuel line using your chosen tool. Make a clean, straight cut to ensure a precise and secure connection. It's important to cut the line at a slight angle to create a better seal when reassembling. Take your time with this step to avoid any accidental cuts or damage to surrounding components.

After cutting the fuel line, you should now have access to the old filter. Remove the filter by unscrewing or unclipping it from its mounting position. Be gentle to avoid damaging the surrounding components. If the filter is stuck, you may need to use a small tool to pry it loose, but be careful not to damage the fuel line or the filter itself.

With the old filter and damaged fuel line removed, you can now proceed to the next steps of your repair, which may include cleaning, replacing, or repairing the fuel system components. Always ensure that you follow manufacturer guidelines and safety protocols when working on fuel-related systems to ensure a safe and effective repair.

Install New Line: Slide the new fuel line into place, ensuring proper alignment

When repairing a broken fuel line, one of the crucial steps is installing a new line to ensure a proper and secure connection. Here's a detailed guide on how to slide the new fuel line into place:

Start by carefully inspecting the damaged fuel line and identifying the point where it needs to be replaced. Locate the fuel filter, as the new line will need to connect to it. Ensure you have the correct replacement line, checking its specifications against the old one to confirm compatibility. Slide the new fuel line into the designated port on the fuel filter.
