FAQs

What Komatsu fuel pump problems show up most on heavy equipment?

Hard starting, stalling under load, low pressure, or repeated air-in-fuel.

Do I need a full pump or just a solenoid/plunger?

If pressure is unstable, check the solenoid and plungers before replacing the full fuel pump.

How do I avoid “no fuel after install”?

Verify flow direction, tighten fittings, replace filters, and fully bleed the system.
