Fuel Tank Vent Tube Sub-Assembly

About this product

The Fuel Tank Vent Tube Sub-Assembly (#77017-42020), a critical body part in the Fuel Tank & Tube system of Toyota vehicles, primarily assists in the proper venting of vapors from the fuel tank. As fuel is consumed, vapors are produced and these need to be carefully vented to prevent pressure build-up. This task is accomplished by the Vent Tube Sub-Assembly, which allows these vapors to escape. When the Vent Tube Sub-Assembly becomes old or blocked, it can disrupt the flow of vapors, leading to potential pressure build-up and fuel inefficiency. Non-functioning Vent Tubes can also lead to increased emissions, making the car less environmentally friendly. Genuine Toyota parts ensure compatibility and are backed by Toyota's genuine parts warranty. By maintaining the correct pressure inside the fuel tank, the Fuel Tank Vent Tube Sub-Assembly (#77017-42020) contributes to fuel efficiency and reduces harmful emissions. It's a small but important part of a well-functioning vehicle.
