Injection Pump Seals & Gasket Kits
Injection pump seal and gasket arrangements vary by family and revision. A leaking housing or shaft does not identify every internal component requiring replacement.

Diesel Seals, Gaskets & Repair Kits
Injection pump, injector, high-pressure oil, EGR and oil cooler seal sets require precise component identification.
Explore Parts for Your Diesel System
Find pump, injector, high-pressure oil, EGR and cooler seal and repair-kit information. The original assembly number helps narrow down the parts you need. Our parts specialists can help with identification and availability questions.
Diesel Injector Seal & O-Ring Kits
Injector installation seals can isolate fuel, oil or combustion gases depending on the engine design. Mixing kit components can cause leakage or fitment problems.
Diesel Fuel-Injection Repair Kits
Repair kits may cover a limited portion of a pump, injector or supply assembly rather than a complete overhaul. Manufacturer revisions can change included pieces.
High-Pressure Oil Seals & Rail Kits
High-pressure oil systems supporting HEUI injection can use specialized rail, standpipe, port-plug and fitting seals. Oil-side leaks have distinct diagnostic implications.
EGR Cooler & Intake Gasket Kits
EGR cooler and valve gasket sets differ by engine and assembly revision. Cooler faults can involve coolant or exhaust pathways rather than fuel injection directly.
Engine Oil Cooler Gasket & Seal Kits
Oil cooler gasket and O-ring designs are determined by the engine and cooler assembly. The wrong seal may not be visible until the system is pressurized.
