FAQ

Q1: Can this injector fit 210‑230HP 6CT engines?

A: No. Higher flow will cause over‑fueling, black smoke and piston overheating.

Q2: Can 4948364 be used for marine service or ISC8.3/CAPS engines?

A: Not for marine/salt‑spray environments, it lacks anti‑corrosion coating — select 3919605 for marine use. Also non‑interchangeable with ISC8.3/CAPS electronic engines as it is purely mechanical

Q3: Can 4948364 replace 3928384 and 3919602?

A: Yes, full 100% interch
