FAQ

Q1: Can I mix 3919602 with 3928384 /4948364 on one same 6CTAA engine?

A: Mechanically they work, hardware parameters are matched. For best cylinder‑to‑cylinder fuel balance, we suggest installing injectors with same marked part‑number for full‑set replacement.

Q2: Can 3919602 work for marine service or ISC8.3/CAPS engines?

A: Not suitable for marine/salt‑spray environments. It has no anti‑corrosion coating, select marine injector 3919605 for marine application. This mechanical injector cannot work with ISC8.3 / CAPS electronic fuel systems.

Q3: What are the exact differences among 3919602, 3928384 and 4948364?
A: All three share identical nozzle, opening pressure and fuel flow, full drop‑in interchangeable.

3919602: Early DCEC factory‑fitted part, also original for CASE 6C8.3 tractors. DCEC production line phased‑out this part number; genuine new stock is very scarce.
3928384: Mid‑term mass‑production DCEC built‑in part, widely stamped on used Chinese construction machinery.
4948364: Cummins global aftermarket unified supersession part, never installed on brand‑new engines, abundant genuine new supply.
