Where is the check valve of Jingyi x5 engine installed?

The engine check valve of Jingyi X5 is usually installed on the fuel pipeline of the fuel supply system. Specifically, the check valve is usually installed on the fuel pipeline between the fuel pump and the intake manifold to prevent the fuel from flowing back. When the engine is running, the fuel pump pumps the fuel out of the fuel tank and sends it to the fuel system, while the check valve prevents the fuel from flowing back to the fuel system from the intake manifold, thus maintaining the normal supply of fuel. If the one-way valve fails, it may lead to engine starting difficulties, fuel economy decline, engine jitter and other problems. If you suspect that there is something wrong with the check valve, it is recommended to send the vehicle to a maintenance center for inspection and maintenance.
