The Wacker Neuson Fuel Pump is a genuine OEM Fuel Pump designed for the RD27-100 and RD27-120 Hydrostatic Vibratory Rollers. Sourced directly from Wacker Neuson, this part carries the same specifications as the component installed on the machine at the factory. It is a direct replacement for all listed RD27-series roller configurations, including both the RD27-100 and RD27-120 variants. When you need an exact-match replacement to get your roller back to work, part number is the correct choice.
Key Features
- Genuine OEM Fuel Delivery Spec — Manufactured to Wacker Neuson's exact flow-rate and pressure specifications for the RD27 roller's diesel fuel system, ensuring the engine receives a consistent, correctly metered fuel supply.
- Drop-In Replacement — Matches the original mounting configuration and port connections of the RD27-100 and RD27-120, allowing straightforward removal and installation without modification to fuel lines or brackets.
- Confirmed RD27-Series Fitment — Verified for RD27-100 and RD27-120 Hydrostatic Vibratory Rollers across all machine numbers listed for those models.
- Sustained Engine Performance — A properly functioning fuel pump maintains steady fuel pressure and volume to the engine. A failing pump causes rough running, power loss, hard starting, or complete shutdown during compaction passes.
- Fuel System Integrity — As a genuine OEM component, this pump meets Wacker Neuson's material and sealing standards for the fuel circuit, reducing the risk of fuel leaks that can create fire hazards on the jobsite.
The fuel pump is responsible for drawing diesel from the tank and delivering it under pressure to the engine's injection system. Without a properly functioning pump, the engine cannot maintain the fuel supply it needs to produce consistent power — leading to stalling, reduced compaction force, or failure to start. On a tandem roller like the RD27, where steady engine output directly drives both drum vibration and hydrostatic propulsion, a worn or failed fuel pump will affect the entire machine's ability to operate. Replacing a failing pump promptly with the correct OEM part restores full engine function and keeps compaction output on spec.
