What to Do When the Fuel Pump is Noisy?

When the fuel pump produces a loud humming noise, it is mainly due to an issue with the gasoline pump. It is recommended to replace the gasoline pump. Below is some information about the gasoline pump: 1. The function of the gasoline pump is to draw gasoline from the fuel tank and deliver it through the pipeline and gasoline filter to the float chamber of the carburetor. 2. It is precisely because of the gasoline pump that the fuel tank can be placed at the rear of the vehicle, far from the engine, and below the engine. Extended Content: To ensure the long-term durability of the generator, the following precautions should be taken: 1. Before installing the fuel transfer pump in the generator set, check whether the model and specifications are correct, and remove the anti-rust oil. The thickness of the selected gasket should be appropriate. To avoid the piston being stuck or not operating properly, prevent the gasket from being too thin or too thick. When tightening the bolts, apply uniform torque to prevent damage to the fuel pump. 2. There is a rubber sealing device between the hand pump piston and the hand pump body on the fuel transfer pump. Do not disassemble it arbitrarily. If the rubber ring is found to be damaged, replace it promptly. 3. The coarse filter screen inside the fuel transfer pump joint is extremely prone to clogging due to debris such as cotton fluff. Regularly inspect and clean it. If the filter screen is damaged, it must be repaired or replaced immediately. 4. Ensure that all sealing gaskets on the generator set's fuel transfer pump are intact. The plastic sealing rings should not be disassembled too many times and should be replaced periodically.
I once experienced extremely loud fuel pump noise while driving, which was really annoying. After checking, common causes include aging of the fuel pump or debris stuck inside. I usually first find a quiet place to confirm if the sound source is from the fuel tank area, then check if the fuel pressure is low. If the pressure is insufficient, it's likely the pump is faulty and needs replacement. Don't take it lightly – stalling on the highway can be dangerous, so I recommend going to a professional repair shop as soon as possible. Using high-quality gasoline and regularly cleaning the fuel filter can reduce debris blockage issues and extend the pump's lifespan. Additionally, improper electrical modifications may also cause abnormal pump operation, so it's safer to consult a reliable technician when making modifications.
