Caterpillar 144-5665 Fuel Injector GP Product Overview
The 144-5665 Fuel Injector GP is a fuel-injection component associated with Caterpillar large-bore diesel engine applications. The current Cat parts catalog identifies 144-5665 as an “INJECTOR GP” and lists compatibility with 3512B, 3508B and 3516B engines in generator-set engine, marine engine and marine auxiliary applications. The Cat catalog currently marks the part number as discontinued and recommends contacting a Cat dealer for appropriate replacement options.
For aftermarket sourcing, engine overhaul, marine maintenance, generator maintenance and international replacement-parts procurement, the number 144-5665 / 1445665 is also found in several industrial cross-reference databases.
Common market references associated with this injector family include:
144-5665, 1445665, 162-8813, 1628813, 229-0197, 2290197, 250-1300, 2501300, 386-1752, 3861752, 392-0200, 3920200, 0R-9944, 0R9944, 10R-1264 and 10R1264.
These numbers should be treated as cross-reference or replacement-search references rather than automatically assumed one-to-one OEM supersessions. Injector calibration can vary according to engine arrangement, serial-number prefix, application, horsepower rating, emissions configuration and fuel-system specification. Final compatibility should therefore be verified against the engine serial number and existing injector number before purchase.
