Volkswagen Fuel Leak

Tolleson’s Popular Service Center for Your Volkswagen’s Fuel Leaks

Post on January 17, 2021 by

Is your Volkswagen suffering abnormally poor gas mileage? It may be due to a fuel leak. Thankfully, fuel leaks can typically be fixed if treated properly. A trusted mechanic will be able to identify the source of the leak and resolve the problem.

This article will cover some of the causes of fuel leaks, how to spot them and the best service center in the Phoenix, Arizona area for getting them fixed.

Common Causes of Fuel Leaks

There are a few different places in the fuel system where gasoline may start to leak out, and some are harder to spot than others.

  • Fuel Injector Seal: The fuel injector is responsible for delivering fuel to the cylinder for combustion. The injector itself will rarely leak. The culprit is most often the o-ring seal around the injector. These wear down over time, and if they break, gasoline can start to escape the engine.
  • Fuel Tank Leak: If the fuel tank is struck by a rock or piece of debris in the road, it may be pierced. The fuel tank may even rot over time if you are driving an old Volkswagen. When the fuel tank is responsible for the leak you will see a puddle of gasoline underneath your car.
  • Leak in Fuel Lines: Fuel lines run from the fuel tank where gasoline is stored to the engine for combustion. These lines are typically made of rubber and are subject to wear and tear over time. Fuel lines are probably the most common location of a fuel leak.

How to Identify a Fuel Leak

There are a few signs that every driver needs to be on the lookout for to spot a fuel leak. The most obvious sign of a fuel leak is a puddle of gasoline under your car.

The smell of gasoline from within your vehicle is another tell-tale sign of a fuel leak that needs to be repaired.

One final sign of a fuel leak is a drop in fuel efficiency, as you’ll be filling up your Volkswagen more, only to have some of that gas lost to a leak. Any of these signs, especially when combined with a check engine light, are indicative of a fuel leak.

Finding the Source of the Leak

You or a mechanic will have to find the source of the leak in order to treat the problem. In order from simplest to most difficult, there are three different ways to find the source of a fuel leak that we’ll discuss.

  • Visual Inspection: To inspect for a leak visually, you’ll want to set your car up on jack stands. Get a flashlight and inspect the fuel tank for a hole, then follow the fuel lines up to the engine to see if the leak is coming from a fuel line.
  • Dyes: If the visual inspection does not give you a conclusive answer, there are certain dyes that can be used to identify the source. When added to the fuel, these dyes will glow under certain lights. Run the engine and apply the light to identify the source of the leak.
  • Leak Detectors: If the other two methods don’t work, a device called a leak detector can be used.

Why You Need to Get Fuel Leaks Fixed Immediately

There are 2 main reasons that you need to get fuel leaks fixed immediately, and they’re both in your own self interest.

First, your car’s fuel efficiency will drop significantly, costing you more and more money out of pocket. Second, fuel leaks are a dangerous fire hazard. Gasoline is highly flammable and will ignite when met with high temperatures. This is especially dangerous if you smoke, as a cigarette butt is enough to start a fire.
