A good gas cap prevents fuel leaks, keeps contaminants out, and ensures that my boat runs smoothly. I learned the hard way that a faulty gas cap could lead to issues like fuel evaporation and engine performance problems.

Identifying When to Replace Your Gas Cap

I’ve discovered that there are several signs indicating it’s time for a gas cap replacement. If I notice fuel odors while the boat is docked or after refueling, that’s my first red flag.
