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.

What Causes the Dragging Sensation When Releasing the Accelerator?

Releasing the accelerator and feeling a dragging sensation in the engine could be related to fuel system cleaning. Improper operation or incorrect installation may lead to this issue, so it is recommended to have it checked by professionals promptly. More details are as follows: 1. Principle of the dragging sensation: Releasing the accelerator triggers the upshift mechanism, causing the engine speed to drop naturally (the extent of the drop depends on the gear ratio difference, typically largest between first and second gears, making the jerking sensation most noticeable and frequent at this stage). The drop in speed naturally reduces the engine's torque output, and since the accelerator is released, the engine torque becomes insufficient. This results in the engine's kinetic output being less than the car's demand, making it feel like the car is dragging the engine. 2. Timing: This issue usually occurs during the shift from first to second gear or second to third gear, as these gear ratios have significant differences. Avoiding this is relatively easy, as it is caused by the upshift triggered by releasing the accelerator.
