FAQ

Q1: What is the exact role of the G105 fuel pump plunger in my engine?
The fuel pump plunger is a precision component inside the injection pump. It pressurizes and meters the exact amount of fuel required for each cylinder. A worn or damaged plunger can cause hard starting, misfiring, reduced power, and increased fuel consumption. Replacing it with a high-quality G105 unit restores proper fuel delivery and engine performance.

Q2: How do I confirm that this G105 plunger is compatible with my specific engine or injection pump?
Compatibility is primarily determined by the OEM number (G105) and physical dimensions. We recommend removing your old plunger and comparing its overall length, diameter, and groove configuration to the new unit. If you are unsure, please provide us with your engine make, model, and serial number, and we will cross-reference it for you.

Q3: What installation precautions should I take for this fuel pump plunger?
Installation must be performed by a qualified diesel technician. Ensure the working area is extremely clean to prevent contamination. Lubricate the plunger with clean diesel fuel or assembly oil before insertion. Do not force the plunger into the barrel. After installation, prime the fuel system and check for leaks before starting the engine. Proper torque specifications must be followed for the injection pump components.
