What are the symptoms of a blocked fuel filter?

A blocked fuel filter affects the engine’s ability to draw fuel, which will affect the power it can generate. At high speeds or heavy acceleration, the vehicle may feel slow and sluggish. If the filter is obstructing the flow of fuel, the engine may not even start.

How often should the fuel filter be changed?

A fuel filter requires regular replacement, inline with the vehicles service schedule, for example every 30,000 miles or two years.

Can I replace my fuel filter on my own?

Replacing a blocked fuel filter can be a very messy job, with the risk of fuel spills. Although the process is simple enough, to ensure your safety and prevent the possibility of causing damage through fuel spilling or contamination, it’s a task best left to the professionals.
