Range comparison

Below, you’ll find the two high-pressure pump references compatible with the Mercedes-Benz OM611 170 CDI 90 HP engine, listed with their key attributes for easy identification and selection.

How to choose

Selecting the right high-pressure pump for your OM611 170 CDI involves checking the engine’s build year, fuel system configuration, and whether the vehicle has undergone performance modifications that may require a higher-flow variant.

1. Verify the pump’s OEM reference against your OM611’s build code to ensure exact compatibility, as slight variations exist between model years and power outputs.
2. Inspect the pump’s condition—look for corrosion on electrical connectors or damage to the camshaft housing, which can indicate internal wear or contamination.
3. Choose a remanufactured unit with a documented core deposit return policy to avoid additional costs and ensure proper recycling of the old pump.
4. Prioritize pumps with a consistent pressure regulation range (e.g., 1,600–2,000 bar) to match the OM611’s 90 HP common rail specifications.
5. Opt for bulk packaging if ordering for a workshop, as individual units often come with higher per-unit costs and limited availability.
6. Check the pump’s rotation direction and inlet/outlet port orientation to prevent installation errors that could damage the fuel system.
7. For modified OM611 engines, select a high-flow variant to accommodate increased fuel demand without triggering pressure relief valve failures.

Storage & logistics

High-pressure pumps for the OM611 170 CDI must be stored in a climate-controlled environment, away from direct sunlight and moisture, to prevent seal degradation and electrical connector corrosion. Bulk shipments should be organized by reference number and build year, with older stock rotated first to maintain freshness. Garages should allocate a dedicated shelf space for these pumps, ensuring they are not exposed to vibration or extreme temperatures that could affect their internal components. Always handle pumps with care, avoiding drops or impacts that might misalign the camshaft or damage the plunger assembly.
