Car Smells of Fuel When Running or Parked: Causes
A fuel smell should always be checked — it can be a fire risk. A Cranbourne West specialist explains.
What it usually means
A petrol or diesel smell can come from a fuel leak (a line, injector, or the tank/filler area), a loose or faulty fuel cap, a leaking injector seal, or evaporative-emissions (EVAP) system faults. A strong fuel smell, fuel stains, or a smell with a check-engine light needs prompt attention.
A raw fuel smell near a hot engine is a potential fire risk — don’t ignore it.
What you should do
Get it checked promptly — especially if the smell is strong or you can see fuel. Check the fuel cap is tight as a first step.
We pressure/leak-test the fuel and EVAP system to find the source and make it safe.
How we find & fix it
Because the same symptom can have several causes, we use dealer-level diagnostics and a methodical check to pinpoint the real cause — rather than throwing parts at it.
