Compatibility / Fitment:

Two hard fitment gates apply:

CPL. The B Series was built across many ratings. Confirm your CPL from the engine dataplate against the list above. If your CPL is not listed, contact us before ordering.

Injector tip size — 7mm or 9mm head. Cummins changed the B Series cylinder head from a 9mm injector bore to 7mm in 1990 to strengthen the head. This injector has the 7mm tip. If your engine has the earlier 9mm head, this injector still fits — but you must install adapter sleeve Cummins 3919358, one per injector. The sleeve converts the bore and seals the injector; replace it whenever the injector is removed. Cummins no longer supplies 9mm injectors.

Injector service parts, available separately: gland nut 2433462041, nozzle nut 2433314182, intermediate disc 2430134023.

Quantity: sold individually. Six for a 6BTA, four for a 4BT.

Common interchanges: 3802325, 3919298, 3802175, 6736-11-3130
