How to use Sea Foam in a Ford Focus with a capless fuel tank? [SOLVED] Asked by Al S. In Alabama I have a 2017 Ford Focus 2.0. How do I get the product into a capless fuel tank?
Hi Al. A Ford vehicle with a capless tank design will accept a gas pump nozzle without needing a funnel. When pouring Sea Foam Motor Treatment into your tank you’ll need a funnel that matches the capless nozzle diameter. All Ford vehicles include an accessory funnel or can be purchased at virtually any auto parts store.
