AP63800AA Ca-terpillar Diesel Fuel Injector for Ca-terpillar 3126 / 3126B 7.2L Engines
AP63800AA is a BP‑code hydraulic electronic unit injector (HEUI) that utilises high‑pressure engine oil and electronic control for precise fuel delivery. It is engineered for Navistar DT466 Transit diesel engines, covering 2000+, 175‑300 HP configurations. It fits a wide range of medium‑duty trucks and transit buses. Cross‑reference numbers include 18300094C92, 2593595C91, 2593597C91 and AP63814BP. Please verify your original injector part number, calibration code, engine serial number and horsepower specification prior to purchase.
Every injector is bench-tested for fuel delivery, injection response, sealing and operating stability. Please confirm the original injector number, AA code, engine serial number and model year before ordering.
