Technical Advice: A functioning valve in the fuel filler cap is essential for the proper operation of the fuel supply system. If the breather valve becomes clogged, a vacuum may form in the tank, manifesting as a sudden drop in engine power or stalling after a few minutes of operation. During every fuel filter replacement, it is advisable to inspect the cap's seal and ensure the filler neck is clean. A leaking or damaged component can lead to fuel contamination by sand and water, which accelerates injector wear.
