Identifying signs of a leaking or damaged fuel line

Identifying the signs of a leaking or damaged fuel line is important because a fuel line leak can make your car use more gas than it should and become much more costly.

This is why, if your car is using more gas than usual, it’s important to find out if there’s a problem with the fuel line and get it fixed as soon as you can.

This quick guide will help you find fuel line issues if there are any, and before they become major problems.

Ways to Tell if Your Fuel Line is Leaking

You Smell a Gaseous Odour

One of the earliest signs that your fuel line might be leaking is if you smell gasoline inside your car while driving. This strong and distinct smell means that the fuel is somehow escaping from where it’s supposed to be within the fuel line.

Gaseous fumes within the interior of the car can cause headaches and nausea for passengers. If you do indeed smell gasoline in your car it should be treated as urgent because it not only means there’s a potential leak, but it also poses a risk of fire or health hazards due to prolonged inhalation of gas fumes.

If you are smelling another odour besides gasoline, read our article What’s That Smell In My Car to find out what odours could be seeping into the cabin of your vehicle.

You See Visible Leaks

If your gas is burning faster than usual, you can check for fuel on the ground where your car was last parked. If you see a leak along the side of your vehicle, around the doors, it’s probably fuel line leak.

These leaks can be seen when parked after long drives or when the vehicle has been sitting for extended periods of time.

If this is the case, take your vehicle to your mechanic because visible leaks can also absorb dust and debris that will eventually seep into the fuel line and cause further deterioration and potential engine problems.

You Feel a Reduction in Engine Performance

A damaged fuel line affects engine performance too. If your vehicle struggles to start, idles roughly, or experiences unexpected power loss, these could be symptoms of fuel line problems.

Also, a compromised fuel line means there’s too much air and not enough fuel in the engine’s combustion chamber which can overheat the car and damage the engine. As you can see, a leaking fuel line could be serious business.

You Hear a Hissing Sound

Sometimes, a damaged fuel line will produce a hissing sound because of the escaping fuel. If you’re not getting the mileage per litre you use to, pay attention to unusual hissing sounds when your vehicle is running. The hissing sounds similar to when a tire is releasing air.

Its most noticeable when the engine is idle or immediately after turning the engine off. The sound may also be accompanied by a drop in fuel efficiency because the fuel system loses pressure, impacting its efficiency.

The Engine Light is On

If something is wrong with the fuel line, sensors can trigger the check engine light. The check engine light can be activated for many reasons, but if it coincides with other problems like fuel odours or performance issues, its worth taking a look at the fuel line. Your mechanic can provide more specific information about the issue.

The Inspections a Mechanic Will Do

Visual Inspection

Regularly inspect the entire length of your fuel line for cracks, wear, or damage. Pay close attention to connections and junctions where leaks are more likely.

Pressure Testing

Professional mechanics use pressure testing to identify leaks in the fuel system. If you suspect an issue, a pressure test can confirm the integrity of your fuel line.

Checking for Corrosion

Corrosion is a common cause of fuel line damage. Inspect for any signs of rust or corrosion, especially in older vehicles or those frequently exposed to harsh environments.

Use of Diagnostic Tools

Specialized diagnostic tools can help detect fuel line issues. These tools are typically available at automotive service centers.

Consult with Your Mechanic

If you can’t do an inspection yourself, or if you have found signs of a fuel line leak or damage, contact your mechanic as soon as possible. They will know what to look for and be able to fix it for you. Most of the time, it’s not an expensive job either, unless there are other underlying issues which should be looked for.

How to Prevent Fuel Line Leaks

Schedule regular maintenance

Regular check-ups by a mechanic can catch early signs of wear and tear in your fuel system, including the fuel line.

Use quality fuel

Using high-quality fuel reduces the risk of clogging and corrosion in the fuel line, which prolongs its lifespan.

Do immediate repairs

Address any issues quickly because delaying repairs can make the problem worse, lead to more damage and higher repair costs.

Keep an eye on fuel consumption

Notice increased fuel consumption and monitor your fuel usage for any unexplained increases.

Avoiding harsh conditions

Minimizing driving during harsh weather conditions like extremely cold days or in corrosive environments. The less wear and tear you put on your vehicle in general, the longer your fuel line will last.
