Yanmar 4-Cylinder Inline Diesel Fuel Injection Pump - Used

Yanmar inline mechanical diesel fuel injection pump for a 4-cylinder Yanmar engine. Four delivery valve outlets, mechanical governor housing, integral feed pump, and flange-mount drive end. A Yanmar data plate is present but the spec number is only partially legible; the tag reads "Yanmar Fuel Injection Pump P# 71488-51300" and must be verified against the Yanmar parts catalog before ordering — exact application is not verified and is sold by photographs, identifiers, and dimensions. Condition: used take-off, untested. Externally complete with surface rust on the drive flange and light corrosion on fittings; paint overspray present. No pop-test, flow-bench, or calibration data is available, so this is offered as an untested unit / rebuildable core. Injection pumps should be bench-tested and calibrated by a qualified diesel injection shop prior to installation. Drained and ports capped before shipping. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
