The part is listed for Caterpillar industrial engines, ship equipment, engine-generator sets, and load, haul, and dump machines. The supplied fitment information identifies the applicable engine and machine models below.

Fitment

• Industrial engines: Caterpillar 3304, 3304B, 3306, and 3306B
• Ship equipment: Caterpillar 3304B
• Engine-generator sets: Caterpillar 3304B
• Load, haul, and dump machines: Caterpillar R1300 and R1300G

Fitment is determined by the engine or machine model and the part number installed in the fuel system. The 3304B engine is listed in the supplied data for industrial engine, ship equipment, and engine-generator set applications. The R1300 and R1300G models are listed under load, haul, and dump equipment.

Before installation, compare the identification number on the removed component with the applicable reference number and verify compatibility with the specific engine configuration. Model designations can cover more than one equipment configuration, so the part number should be used together with the machine or engine model during parts selection.
