If you smell gasoline around your vehicle, have the fuel system inspected immediately for leaks
After filling up with bad gas, have the tank drained and the fuel filter replaced before driving further

Frequently Asked Questions

How much does a fuel pump replacement cost in Cornwall? +
Fuel pump replacement typically costs $600-$1,200 for most vehicles, including parts and labor. The pump is usually located inside the fuel tank, making access and labor the primary cost drivers.
How often should fuel injectors be cleaned? +
Professional fuel injector cleaning is recommended every 50,000-80,000 km. Using quality fuel with detergent additives and periodic fuel system cleaner additives can help extend this interval.
Can bad gas damage my engine? +
Yes, contaminated fuel containing water or excessive debris can damage fuel injectors, clog filters, and cause misfires that harm the catalytic converter. If your engine runs rough immediately after filling up, suspect bad gas.
How do I know if my fuel filter is clogged? +
Common symptoms include difficulty starting, loss of power under load, engine stalling, and the car jerking during acceleration. A fuel pressure test can confirm if the filter is restricting flow.
