Fuel Cap Video
A fuel cap, also known as a gas cap, protects your fuel supply by sealing and providing cover for your fuel tank. Fuel caps are designed to prevent fuel loss and keep out contamination. Without a functioning fuel cap, gas will evaporate and reduce your fuel efficiency by 1-2%. If your fuel cap is missing, you could potentially introduce contaminants that can clog your fuel filter. One of the more common causes of an illuminated check engine light is a loose, or missing fuel cap. If you suspect your fuel cap needs to be replaced, or your check engine light is on, give All Tune and Lube Total Car Care in Cedar Rapids a call at 319-550-3390.
