Fuel Injection Pump 1J730-51012 — OEM-Spec Replacement for Kubota V2607 / V2607T Engine

At nearly $1,000, a fuel injection pump is one of the most significant service investments on a Kubota excavator — and one of the most consequential. This brand-new OEM-spec pump is a direct bolt-on replacement for part number 1J730-51012 / 1J73051012, precision-calibrated to match the original's flow rate, pressure output, and injection timing for the Kubota V2607 engine family. Restore full power, fuel efficiency, and reliable starts — and protect the rest of your fuel system from the downstream damage a failing pump causes.

Why Replace Your Fuel Injection Pump?

A failing injection pump doesn't just hurt performance — it puts your entire fuel system at risk. Symptoms include hard starts, loss of power, excessive smoke, and rising fuel consumption. Left unaddressed, low fuel pressure accelerates injector wear and can cause catastrophic engine damage. A new pump is the right fix — and far less costly than the alternative.
