Perkins original Perkins 20R-8067 Diesel C7 Injector 387-9441 20R-8066 328-2587 295-9166 for Excavator E324D E325D new injector original new injector

The Perkins® Reman fuel injector 20R-8067 is an original remanufactured injector built specifically for the Perkins C7 diesel engine family, including C7 2.2 SF variants used in marine propulsion, industrial generator sets, construction machinery, and stationary power units. Each unit carries OE-number traceability and is produced under Perkins reman programs that apply specialized metallurgy, proprietary processes, engineering updates, and extensive end-of-line testing to deliver like-new reliability for heavy-duty maintenance and overhaul operations.

The authorized cross-reference set covers 20R8067, 387-9441, 295-9166, 328-2587, 10R-7226, 280-4173, 280-4174, 557-7627, 20R-9079, and H1315B, allowing distributors and fleet buyers to consolidate inventory around a single C7 injector part. The injector is engineered for modern low-sulfur and low-lubricity diesel fuels and is suitable for original reman, aftermarket replacement, new replacement, and rebuilt injector channels. C9 or C-9 engine compatibility must not be assumed; installers should always confirm by matching the original injector number and engine serial number before order shipment.

Reliable service life depends on clean diesel supply and scheduled maintenance. Operators should replace fuel filters on interval, drain water separators, inspect fuel lines, and test injector return flow when symptoms appear, while replacing sealing components during installation. Common C7 failure indicators include hard starting, rough idle, black or white smoke, elevated fuel consumption, misfire, power loss, diesel knock, excessive return fuel, fuel dilution in engine oil, and uneven exhaust temperature. Recommended diagnostics include fuel pressure testing, return flow testing, cylinder balance testing, scan tool analysis, injector bench testing, and fuel quality inspection, since water contamination, dirty filters, and metallic debris remain leading causes of injector damage.
