375-2649 is supplied as a remanufactured replacement fuel injection part. Cross-reference numbers: 375-2649, 3752649, 323D2L. Application recorded for this part: C7.1. This is the last precision component in the fuel path. Everything upstream exists to deliver clean fuel at stable pressure; this unit decides when combustion starts and how completely the charge burns. That is why injector condition shows up so directly in noise, smoke and emissions. Watch for hard hot starting, uneven idle, visible smoke, a misfire that clears when the engine is revved, and consumption creeping up without any change in operating conditions. A back-leakage comparison across the set is the cheapest meaningful test: uneven return between cylinders points at the failing unit. Follow it with a cut-out test to confirm which cylinder actually stops contributing. Before fitting: clean the seat thoroughly, use new copper washers and seals, and torque the clamp to the engine manufacturer’s figure. Replace as a set where possible, and check whether the ECU needs the new units’ classification codes written in afterwards. Rebuild process: full teardown and measurement first, then replacement of all wear components, machining back to specification where required, followed by calibration and bench testing. The difference between this and a cleaned used part is the measurement and test record — we hold every unit to the specification for the part number, not just to 'it runs'. Test sheets available on request, and every unit ships with a 12-month warranty.
