Mercedes Sprinter Fuel Rail / Fuel Distributor – Genuine OEM | VS30 2.0L OM654 Diesel | #6540700195 (2023+)

A cracked, leaking, or pressure-compromised fuel rail on a VS30 Sprinter collapses the high-pressure fuel supply to every injector simultaneously — causing misfires, rough running, power loss, and hard starts that won't resolve until rail integrity is restored. This is the Genuine Mercedes-Benz OEM fuel rail for VS30 Sprinters equipped with the 2.0L OM654 diesel engine, a direct replacement that restores the pressurized fuel distribution required for precise common-rail injection operation.

What This Part Does

The fuel rail — also called a fuel distributor — is the high-pressure accumulator that connects the outlet of the high-pressure fuel pump to each of the four fuel injectors. It stores diesel at the extreme pressures the OM654's 4th-generation common-rail system operates at — up to 2,700 bar — and distributes that pressurized fuel on demand to each injector as the ECU commands firing events. The rail's job is to act as a buffer, absorbing the pressure pulses generated by the high-pressure pump and maintaining a stable supply pressure so that each injector receives the same consistent rail pressure regardless of cylinder firing order or load. The integrated fuel pressure sensor monitors rail pressure continuously, feeding that data back to the ECU for fuel metering control. When the rail develops a micro-crack, a sealing failure at an injector port, or a connection leak, pressure drops erratically across all cylinders — causing rough combustion, fault codes, and progressive performance loss.

Common Symptoms of a Failing Fuel Rail

• Rough idle, misfires, or uneven power across cylinders with no single-injector fault isolated
• Hard starting or extended cranking as rail pressure fails to build to the required threshold
• Rail pressure fault codes or fuel system pressure plausibility codes from the ECU
• Fuel odor from the engine bay or visible diesel seepage at rail connection points or injector ports
• Power loss under load that corresponds to rail pressure dropping below specification

When to Replace

Replace when the rail is confirmed leaking, cracked, or when pressure testing reveals it cannot hold specification. Also replace when performing a full injection system overhaul — new injectors on a rail with a compromised pressure boundary will not deliver the injection consistency the OM654 requires. Always replace all injector sealing washers and o-rings when the rail is removed, and replace the fuel filter at the same time.

VS30 OM654 Specific — VIN Verification Required

This fuel rail is for VS30 Sprinters equipped with the 2.0L OM654 diesel engine. It is not compatible with VS30 models equipped with the 3.0L OM642 or NCV3 Sprinters equipped with the 2.1L OM651. Always verify your engine code and VIN before ordering. Contact us and we'll confirm fitment before you buy.
