Fuel Injector 116-7150 / 160-1697 — New Aftermarket Replacement for Caterpillar CAT 3126 Engine

The CAT 3126 is one of Caterpillar's most widely deployed diesel engines — found in medium-duty trucks, school buses, municipal equipment, and the 30/30 Deuce tractor. When an injector fails, the symptoms are hard to ignore: rough idle, hard starts, black smoke, power loss, and fuel economy that tanks. This new aftermarket injector restores factory-spec fuel atomization and injection pressure, eliminating those symptoms at the source and protecting your engine from the downstream damage a failing injector causes.

Why This Injector

• OEM-Matched Specifications — Engineered to match Caterpillar's original spray pattern, flow rate, and injection pressure for the 3126 engine
• Precision Nozzle Atomization — Fine-mist fuel delivery ensures complete combustion, restoring power output and fuel efficiency
• Tested to OEM Pressure & Flow Standards — Verified performance before shipping; no guesswork on a $543 purchase
