3406 Fuel System Components

As the only Caterpillar-dedicated firm in the U.S. with an exclusive focus on the legendary 3200, 3300, and 3400 family of engines, we are happy to answer any questions you have.

3406 fuel system components:    This section includes Mechanical Fuel Injectors, Water Pump Components, Cylinder Liners, Turbocharger Components, Bushings, Bearings, Seals, Gaskets, Gasket Sets, Overhaul kits, and all other products. 

Our humble origins began by setting out to establish a new industry-leading standard for remanufacturing caterpillar fuel injection pumps. We are also happy to help you through this important purchase process, including helping you diagnose any problem you’re having with your current fuel injection pump.

Custom Work:  We are happy to custom build a fuel injection pump system to meet your needs.   Our  engine services are limited to rebuilds with high performance additions.  We will soon post available high performance options on the Shop page.

Current Parts Availability:  We supply most parts for the 3400 series now.  We can get just about any other part you need with a quote request or call.  For these parts, it might take an extra day to ship.
