• OEM Fuel Metering Accuracy — Calibrated to the factory injection timing and fuel delivery rate required by the RW1403HF engine, maintaining consistent combustion and engine response.
• Direct Bolt-On Replacement — Matches the original mounting configuration and fuel line connections on RW1403HF rollers, allowing straightforward swap-out during service.
• Confirmed RW1403HF Fitment — Verified for RW1403HF RAMMAX walk-behind rollers; always cross-reference part number 5360331 before ordering.
• Restored Engine Performance — A properly functioning injection pump delivers fuel at the correct pressure and volume, keeping the roller's engine running smoothly through continuous compaction passes.
• Fuel System Integrity — As a genuine OEM part, the 5360331 meets the sealing and pressure tolerances specified for the fuel system, helping prevent fuel leaks and injection faults that can sideline equipment.

The fuel injection pump is responsible for pressurizing and metering diesel fuel from the tank to the engine's injectors at precisely the right volume and timing. On walk-behind rollers like the RW1403HF, consistent fuel delivery is critical to maintaining steady engine speed under the variable load demands of compaction work. When the injection pump wears or fails, symptoms typically include hard starting, rough idle, loss of power, or excessive smoke — all of which point to compromised fuel pressure or metering that only a correctly spec'd replacement pump can resolve.
