The Caterpillar C7 Series Fuel Injector 328-2587 (alternately formatted 3282587) is an industrial-grade common rail diesel Injector GP Fuel, purpose-built for Caterpillar C7 diesel engine fuel systems. It delivers precisely metered diesel fuel into the combustion chamber at the correct timing, pressure and spray pattern to support stable, reliable heavy-duty engine operation. It is available in new, OEM-type, aftermarket replacement or remanufactured condition per supplier stock to meet varied B2B procurement demands.

Verified associated references include related reman replacement number 20R-8067 (also 20R8067) and common cross-reference number 387-9441 (also 3879441). Though some aftermarket listings link the part to C9 engine applications, neither cross numbers nor extended fitment claims are universally interchangeable. All compatibility must be confirmed via engine/machine serial number, original injector part number, ECM calibration and fuel system configuration prior to ordering.

This injector supports heavy-duty use cases across construction, industrial, marine and truck/fleet sectors, with verified equipment compatibility for CAT 950H, 962H, 584, M325D MH and M325D L MH units, plus loaders, excavators and material handlers. It is tailored for B2B stakeholders including repair workshops, fleet maintenance teams, engine rebuilders, marine suppliers, equipment service firms and aftermarket distributors for scheduled maintenance and repair needs.
