17099-85G00 Fuel Pump Gasket for Komatsu K21 K25 Engines

Overview

The 17099-85G00 GASKET,FUEL PUMP is a genuine sealing component for Komatsu K21 and K25 forklift engines. Fitted between the fuel pump and the engine case, it blocks fuel leaks, keeps air out of the fuel line, and helps the pump maintain consistent delivery to the engine. A worn or crushed gasket often shows up as hard starting, rough running, fuel odors, or visible weeping around the pump mount. Replacing it with the exact-fit 17099-85G00 restores a tight seal and dependable fuel supply.

Compatibility

This gasket fits Komatsu engines across the K21 and K25 series, including:

• K21 series: K21-1X3-TO, K21-1XL-FM
• K25 series: K25-1BL-FM

The 17099-85G00 for K21-1X3-TO is the same part specified for the other listed engines, since these units share the fuel pump mounting design. If your engine tag shows a different suffix, verify the number against your Komatsu parts manual or contact our team with your model and serial number before ordering.

Quality and Reliability

Komatsu engineered the 17099-85G00 to the exact thickness, hole pattern, and compressibility that the K21/K25 fuel pump mounting surface requires. The gasket material resists softening in continuous contact with fuel and holds its shape under engine heat and vibration, so the seal stays intact through repeated heat cycles. Because it matches the original drawing, it seats flat on the first install with no trimming or improvised shimming needed.

Installation and Maintenance Tips

• Relieve fuel system pressure and disconnect the battery before starting work.
• Remove the fuel pump and clean both mating faces thoroughly; leftover gasket residue prevents a flat, leak-free seat.
• Fit the new 17099-85G00 dry, align the bolt holes, and tighten the fasteners evenly in a criss-cross pattern to the torque value in the Komatsu service manual.
• Reconnect the fuel line, start the engine, and inspect the pump perimeter for drips or weeping.
• Inspect the gasket whenever you service the fuel system, and always fit a new gasket on reassembly rather than reusing the old one.
