Perkins original  155-1819 FUEL INJECTOR GP Replacement for 156-4727 157-3727 154-3337 EX639348 3126 3126B 3126E C7 7.2L Diesel Engine Part original new injector

The Perkins 3126 diesel fuel injector is engineered as a direct OEM equivalent for OE number 155-1819, supporting the full Perkins 3126 engine family including the 3126B and 3126E variants. Built from hardened alloy steel and assembled under strict OEM equivalent tolerances, each unit is 100% performance tested prior to shipment to verify spray pattern, flow rate, and solenoid response. The electronic unit injector design delivers precisely metered fuel at high pressure, ensuring efficient atomization for cleaner combustion across industrial, marine, generator, and heavy-duty truck applications.

This injector carries broad cross-reference compatibility, replacing part numbers 157-3727, 173-1012, 173-4566, 173-9379, 188-1320, 222-5965, 145-9360, 0R-9348, EX639348, and OR9348. The remanufactured exchange option under reference 0R-9348 / EX639348 / OR9348 provides a cost-effective solution without compromising performance. Proper installation requires a clean injector bore, replacement of the copper sealing washer, lubrication of O-rings, application of OEM torque specifications, fuel system bleeding, and verification of injector coding where applicable to maintain optimal engine operation.

Operators relying on Perkins 315, 317, and 318 excavators, IT28G wheel loaders, diesel generator sets, commercial marine vessels, medium and heavy-duty trucks, pumping units, compressors, and agricultural machinery benefit from improved fuel efficiency, lower emissions, enhanced cold-start capability, reduced engine noise, and greater overall power output. The 12-month warranty reflects the manufacturer's commitment to long-term reliability across demanding duty cycles in construction, power generation, marine, transportation, and industrial sectors.
