The Problem
Fuel Smells Should Never Be Dismissed
Modern fuel systems are designed to be completely sealed. When you can smell fuel, it means that seal has been broken somewhere. The source could be anything from a minor component to a more significant leak — and the right answer depends on your vehicle's make, model, fuel type and age.
🚨
If the fuel smell is strong or you can see a visible leak, do not start the engine. Fuel vapour near a hot engine or ignition source is a fire risk. Get it inspected before driving.
