Fuel Filter Cap

A fuel filter cap provides a tight seal for the filter and protects the engine by preventing fuel leaks and contaminants in the fuel system. The cap on your fuel filter also helps protect the filter from damage and premature failure. Over time, the cap can become less effective due to failing seals or damage. Signs of a bad or clogged fuel filter include hard starting, decreased power, engine misfire, and lack of acceleration. If the cap has failed, you may also notice fuel leaks or a fuel smell.
