The fuel cap (oil cap/fuel cap) is a seemingly simple but essential component of a chainsaw. It seals the tank, prevents fuel evaporation and oil leakage, and plays a crucial role in equalizing air pressure inside and outside the tank. A faulty cap can cause the following problems: oil or fuel leakage after the chainsaw is switched off, starting difficulties or stalling during operation (due to insufficient fuel supply caused by negative pressure in the tank), a strong smell of gasoline around the tank, or even water ingress into the tank, which can lead to engine damage. This product is specifically designed for many popular Husqvarna chainsaws, including models 365, 372, 385, 390, 394, and 395. The fuel cap features a double seal with an integrated, high-quality, oil-resistant O-ring that ensures a tight and reliable closure. It will not loosen and remains sealed even under strong chainsaw vibrations. An integrated check valve in the cap ensures a consistent fuel supply. During chainsaw operation, the fuel in the tank is gradually consumed. The check valve automatically introduces air to equalize the internal and external pressure, preventing fuel supply interruptions caused by vacuum. It also prevents fuel leaks when the chainsaw is tilted. The tank cap, made of oil- and weather-resistant plastic, is characterized by excellent aging and corrosion resistance, as well as a long service life. Its dimensions precisely match the original specifications; simply replacing a worn or damaged cap restores optimal sealing and venting. This high-quality replacement part offers an economical maintenance solution. It is recommended to regularly inspect the cap's seal. If the seal is worn and hardened, the cap body is cracked, or the check valve is clogged, the cap must be replaced immediately to ensure proper operation and safe use of the chainsaw.
