Changing fuel lines is a messy and time-consuming job, but it is possible to do it yourself if you have the right tools and safety equipment. Fuel lines are the rubber, metal, or plastic pipes that carry gasoline from the fuel tank to the fuel pump, and then into the engine's combustion chamber. Over time, these lines can become corroded, cracked, or broken, leading to fuel leaks. While there is no set time frame for when to replace fuel lines, it is recommended to do so when they show signs of deterioration or every 3-5 years for marine fuel lines.

What You'll Learn
When to replace fuel lines
The fuel lines in your car are rubber, metal, or plastic pipes that carry gasoline from the fuel tank to the fuel pump, which then squirts the fuel into the engine's combustion chamber. Given the crucial role they play in your car's performance, the fuel system is not something to be taken lightly.
Fuel lines should be replaced when they are old, cracked, or broken. If your car is leaking fuel onto the pavement or you can constantly smell gasoline, you may have a damaged fuel hose. The main reason metal fuel lines fail is corrosion, which can be caused by abrasive materials removing the paint or coating on the line. This can occur at a mounting bracket or from debris kicked up from a tire.
It is recommended to replace all four sections of a rubber fuel line every five years. Additionally, it is advised to inspect the fuel hose every six months by bending it over 180 degrees; if it cracks or is stiff, it needs to be replaced.
If you notice any issues with your fuel lines, it is important to have them properly diagnosed by a technician certified in automotive maintenance. While some auto repairs can be done at home, replacing a broken or damaged fuel hose typically requires a professional mechanic to ensure safety and avoid further issues.

When to Replace Fuel Lines
Fuel lines should be replaced when they show signs of deterioration, such as cracking or stiffness. In addition, fuel lines that are exposed to sunlight may need to be replaced more frequently, as they are more susceptible to damage. It is recommended to replace fuel lines every 3-5 years, or at least inspect them for any signs of damage.
Steps to Replace Fuel Lines
- Purchase replacement fuel lines and clamps: Buy the correct size of fuel hoses and fuel hose clamps for your vehicle, based on its make, model, and year.
- Gather the necessary tools: You will need a screwdriver, pliers, a knife, a floor jack, jack stands, vice grips, and protective gear such as eye protection and old clothes.
- Prepare your car: Lift the vehicle using a floor jack and secure it with jack stands. Locate the fuel lines and fuel filter, which is usually in the engine bay under the hood but can also be at the rear of the vehicle near the gas tank.
- Relieve the pressure in the fuel system: Locate the fuel pump fuse or relay in the fuse box and remove it while the engine is running. This will relieve the pressure in the fuel system.
- Disconnect the battery: Disconnect and isolate the negative terminal on the car's battery to avoid any chance of an electric spark during the repair.
- Remove the old fuel hoses: Get underneath the car, locate the fuel filter, and remove the plastic shield surrounding it. Place a catch pan or towel underneath to catch any leaking gasoline. Loosen the hose clamps with a screwdriver or wrench and remove the fuel hose. Locate and remove the other end of the old fuel hose.
- Install the new fuel line: Put the new hose clamps over the new fuel line, keeping them loose for now. Slide the open ends of the fuel hose into place, ensuring that the hardware faces you for easy access to tighten the clamps.
- Check the fit and tighten the clamps: If the hose is too long, cut a small portion off the ends until it fits perfectly. Once the fit is correct, tighten the clamps with a screwdriver until the hose is firmly in place.
- Reconnect the battery and pressurize the fuel system: Reconnect the negative terminal on the car's battery and return the fuel pump fuse to the fuse box to pressurize the fuel system.
- Start the engine and inspect for leaks: Turn on the engine and inspect your work for any fuel leaks. If you find a leak, shut off the engine and repair it immediately, following the necessary safety precautions.
Additional Tips:
- It is recommended to change the fuel filter at the same time as replacing the fuel lines.
- Always work in a well-ventilated area and have a fire extinguisher nearby when working with gasoline.
- Consult your vehicle's service manual or a technician for specific information and tips about your car's fuel system.
By following these steps, you can safely and effectively replace the fuel lines in your vehicle, ensuring a properly functioning fuel system and avoiding potential leaks or delivery problems.

Safety precautions when replacing fuel lines
Safety should be a top priority when replacing fuel lines. Here are some detailed safety precautions to follow:
Work in a Well-Ventilated Area and Avoid Gas Fumes
It is important to work in a well-ventilated area to avoid inhaling gas fumes, which can be dangerous. Keep the work area open and ensure there is adequate airflow to prevent the buildup of fumes.
Have a Fire Extinguisher On Hand
Keep a fire extinguisher nearby in case of any accidental fires or sparks. Working with flammable liquids like gasoline always carries a risk of fire, so it is essential to be prepared.
Avoid Using Tools That Can Create Sparks
Do not use tools that can create sparks, such as power tools or metal tools that may cause sparks when striking another object. Opt for hand tools instead, and ensure they are in good condition to reduce the risk of sparks.
Wear Appropriate Protective Gear
Wear protective clothing, such as old clothes that cover your arms and legs, to avoid getting gasoline on your skin. Also, consider wearing eye protection, such as safety goggles, to shield your eyes from any splashes or debris.
Disconnect the Battery
Before beginning any work on the fuel system, disconnect the negative terminal on the car's battery to prevent any chance of an electric spark. This is an important step to reduce the risk of fire or explosion.
Relieve Pressure in the Fuel System
Most cars today use fuel injection systems that operate at high pressures. Relieve the pressure in the fuel system before removing any fuel hoses to avoid gasoline spraying everywhere. Locate the fuel pump fuse or relay in the fuse box and remove it while the engine is running to depressurize the system.
Use Properly Sized and Rated Hoses and Clamps
Ensure that you purchase and use the correct size and type of fuel hoses and clamps for your vehicle. Using improperly sized or rated hoses and clamps can lead to leaks and unsafe conditions. Consult with auto shops or online sources to get the right parts for your specific vehicle.
Clean Up Any Spills Immediately
Gasoline is highly flammable, so clean up any spills or leaks immediately. Have rags, absorbent materials, and a plastic sheet underneath the vehicle to catch any drips or spills. Dispose of the used materials properly, following local regulations for flammable waste.
Consult a Professional if Needed
If you are unsure about any part of the process or feel uncomfortable performing the replacement, consult a professional mechanic or technician. They have the training and experience to handle fuel system repairs safely.
Remember, working on a fuel system can be dangerous, so take your time, follow instructions, and prioritize safety at every step.

Signs that fuel lines need replacing
The fuel line is the rubber, metal, or plastic pipe that carries gasoline from the fuel tank to the fuel pump, which then squirts the fuel into the engine's combustion chamber. As vehicles are lasting longer, the chances of fuel lines springing a leak are increasing.
- Corrosion: The main reason metal fuel lines fail is due to corrosion. Corrosion usually occurs when abrasive materials start to remove the paint or coating on the line. This can happen at a mounting bracket or from debris kicked up from the tire.
- Old, cracked, or broken fuel lines: If your fuel line is old, cracked, or broken, it needs to be replaced immediately.
- Fuel leaks: If you find your fuel leaking onto the pavement, your fuel line may need to be replaced.
- Constant smell of gasoline: If you can smell gasoline constantly, this could be due to a fuel hose problem.
- Fuel hose stiffness or cracking: It is recommended that you inspect your fuel hose every six months. Bend it over 180 degrees, and if it cracks or is stiff, it needs to be replaced.
