What is the pipe above the fuel tank?
1 Answers
The pipes above the fuel tank are as follows: 1. Fuel outlet pipe: Delivers gasoline through the motor. 2. Fuel return pipe: Returns unused gasoline from the fuel injector back to the fuel tank. 3. Fuel vapor collection pipe: Gasoline is highly volatile. To prevent gasoline evaporation in the fuel tank, which causes air pollution and fuel waste, an activated carbon canister is installed. It connects to the fuel tank and intake manifold via pipes, using this activated carbon canister to absorb gasoline vapor from the fuel tank. Then, when the vehicle is operating, the gasoline in the canister volatilizes again to supply fuel to the engine.
