The Wacker Neuson Fuel Injection Valve is a genuine OEM component designed for the RS800H Single Drum Vibratory Roller. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component installed at the factory. If you're servicing or rebuilding the fuel system on an RS800H, the ensures a correct, like-for-like replacement with no guesswork on compatibility.
Key Features
- OEM-Calibrated Flow and Spray Pattern — Manufactured to the precise metering and atomization specifications required by the RS800H engine, ensuring the correct fuel charge is delivered on every injection cycle.
- Direct Swap Installation — Matches the original valve's port geometry, thread spec, and connector interface, so it seats and seals exactly as the removed part did.
- Confirmed RS800H Fitment — Verified for the RS800H Single Drum Vibratory Roller, so you can order with confidence before the machine ever hits the bench.
- Protects Engine Performance Under Load — A functioning fuel injection valve keeps combustion consistent during compaction work; a worn or leaking valve causes rough running, power loss, and excessive fuel consumption.
- Fuel System Safety — As a pressurized fuel system component, using a genuine OEM valve rated to the correct operating pressure helps prevent fuel leaks that can create fire hazards on the worksite.
The fuel injection valve controls the precise timing and volume of fuel delivered into the engine's combustion chamber. It works under high pressure to atomize fuel into a fine mist, enabling clean, efficient combustion with each engine cycle. When the valve wears, sticks, or begins to leak, the engine can run rough, lose power, consume excess fuel, or fail to start — making prompt replacement critical to keeping the roller operating safely and efficiently.
