Fuel filters are designed to catch stray particulate matter in fuel before they reach the engine. This helps keep the engine performing optimally.
The fuel filter is typically found somewhere between a vehicle’s engine and fuel tank. It’s usually inside the fuel tank itself in the opening of the fuel line or along the fuel line running underneath your vehicle.
The exact location of the fuel filter depends on the vehicle’s make and model. For instance, if you own a 2002 Toyota Corolla, the fuel filter can be found underneath the rear seat cushions. It’s inside the fuel tank as part of the fuel pump assembly. Meanwhile, the 1995-2002 Honda Accord models have the fuel filter near the brake master cylinder on the back of the engine.
Tips on How to Access the Fuel Filter
Before you access your fuel filter, it’s important to first relieve the pressure in the fuel system. You can usually do this by allowing your engine to run for a minute or so without the fuel pump functioning.
You’ll also likely need to disassemble any parts sitting over the filter such as the intake manifold. Some vehicles will have their fuel pump and thus their filter in the back of the vehicle, which means you’ll need to go into the trunk to access it. There might also be clips holding the filter in place that you’ll need to unfasten before pulling it out. In the end, it’s best to check your vehicle’s repair manual if you’re having a difficult time locating the fuel filter.
