Fuel Injection Pump 16006-51010 for Kubota Engine D662 D722 D782 D902

This fuel pump is built to meet or exceed the original specs for Kubota Engine D662 D722 D782 D902. The fuel pump is the heart of the fuel delivery system — it moves fuel from the tank to the engine at the correct pressure and flow rate. A failing pump doesn’t usually give much warning before it leaves you stranded.

Signs You Need a Replacement

If your equipment is showing any of these symptoms, the injection pump may be the cause:

• Engine cranks but won’t start — no fuel reaching the injectors
• Stalling under load — engine dies when you demand more power
• Loss of power at high RPM — fuel delivery drops off at higher engine speeds
• Whining noise from fuel tank area — the pump bearings are wearing out
• Engine surging or bucking — inconsistent fuel pressure causes hesitation
• Hard starting after sitting — fuel drains back through a weak check valve

Before You Replace the Pump

Before replacing the fuel pump, check the fuel filter first — a clogged filter causes the same symptoms and costs a fraction of the price. If you confirm the pump is bad, replace the fuel filter at the same time. A restricted filter is often what killed the old pump. After installation, cycle the key to ON several times (without starting) to prime the system and bleed out any air before cranking the engine.

How do I check if my engine code (BX24D, BX25, RTV900G, RTV900R) matches?
The engine code is stamped on a metal tag attached to the engine block, usually near the timing belt cover or on the cylinder head. Compare the code you find with the list above. Engine codes are 3 to 6 characters long and use a combination of letters and numbers.

My vehicle is a 6006 model — is it covered?
The compatibility range for this part includes 6006-5101. The 6006 model year falls within this range, but you should still verify the engine code and body type match. Mid-year production changes sometimes mean two vehicles from the same model year use different parts.
