What are the impacts of a leaking return fuel pipe?
1 Answers
The impacts of a leaking return fuel pipe are as follows: 1. Fuel supply mode: It is divided into electronic injection vehicles and carburetor-type fuel supply modes. If it is an electronic injection vehicle fuel supply mode, it is further divided into single-pipeline and dual-pipeline fuel supply modes. 2. Electronic injection: The dual-pipeline mode has two fuel pipes, one for supplying fuel to the vehicle. The other returns excess fuel to the fuel tank through the fuel pressure regulator and return fuel pipe. If the leakage is caused by this mode, tightening is sufficient. 3. Carburetor type: If it is a carburetor-type fuel supply mode, it may be caused by reasons such as excessively high carburetor fuel level or incorrect float needle valve position. Cleaning the carburetor is sufficient.
