What causes the fuel pump bearings to wear out?
With a near-empty tank, the fuel system is suddenly pushing air instead of diesel fuel. Anything but diesel fuel can wear out the fuel pump bearings, which means the fuel injectors will not receive the fuel at the pressurized level (30,000 psi, 40,000 psi, etc.) it should be.
When to replace fuel pump on Kawasaki small engine?
Kawasaki Fuel Pump: If your Kawasaki small engine isn’t starting or if you’re having problems keeping it running, the fuel pump may be the problem. Find the correct Kawasaki replacement fuel pump you need below. We also suggest using a Fuel Stabilizer to help prevent fuel system problems.
What causes a diesel fuel pump to back up?
A clean diesel fuel pump injector is a happy diesel fuel pump injector. Over time, residue can build up in the fuel system, and enough gunk, grime and grease can clog up the entire fuel injector pump. The spray tip (where the fuel leaves the injector and enters the combustion chamber) is particularly prone to “backing up,” so to speak.
How much pressure does a fuel injection pump have?
Pressure-Packed Fuel Injection Today’s diesel fuel injection pumps are under pressure – even more pressure than what was once considered “normal.” Around 15-20 years ago, it was common for fuel injector pumps to process fuel in a system at around 10,000 to 15,000 psi (pounds per square inch).

Why is the fuel pump and relay not working?
The ignition circuit, which includes the ignition switch, controls power to many components, including the fuel pump and relay. If there is an issue with the switch or the circuit, perhaps a wiring problem, then power to the fuel system may be cut off.
How can you tell if your fuel pump is failing?
If you ignore all of the other warning signs of a failing fuel pump, it will eventually fail completely. Once your fuel pump has finally given up the ghost, no fuel will reach your engine. You may hear your spark plugs firing when you try to start your car, but without fuel, the engine won’t be able to turn over.
