Our specialty is diesel fuel injection: fuel injectors, CP3 and CP4 high-pressure pumps, VP and other injection pumps, turbochargers, sensors, and EGR components.

On the road, that means Ford Powerstroke, Ram Cummins, GM Duramax, VW TDI, and Detroit Diesel.

Off the road, we cover heavy equipment and agricultural engines from Bobcat, Doosan, Case New Holland, Deutz, Komatsu, Kubota, and Yanmar.

On the water, San Diego is one of the largest boating communities on the West Coast — and our shelves reflect it. We carry injectors and injection pumps for Volvo Penta, marine Cummins (6BT and 6CTA through the QSB and QSK series), Caterpillar 3208, MAN, MTU, Perkins, and Yanmar. Add Holset and BorgWarner marine turbochargers, and that covers everything from sailboat auxiliaries to sportfishing boats to commercial vessels.

Every part we sell is genuine. We're an authorized Bosch dealer, and the other brands we carry — Cummins, Delphi, Garrett, Stanadyne, BorgWarner, Denso, Holset, IHI, AMBAC, and Zexel — come to us through authorized distributors only.

Diesel fuel system parts are unforgiving on fitment. If you're not certain a part number matches your engine, message us in the chat bubble in the bottom-right corner of your screen — send your part number, cross number, or engine details and we'll verify against the OEM cross-reference before you order.
