This is a brand new JCM fuel rail pressure relief regulator valve, designed for Mercedes Sprinter and Vito vans with the 2.1 and 2.2 CDI diesel engines.
It's a screw-in type with a 2-pin connector, and it's a direct fit for many common rail diesel applications.
The main OEM number is A6110780549 (also 6110780549), and it crosses with 0281002698 and a ton of others.
It fits models like the C 200 CDI, C 220 CDI, E 200 CDI, E 220 CDI, ML 270 CDI, and various Sprinter models (208, 211, 213, 216, 308, 311, 313, 316, 408, 411, 413 CDI).

It's a diesel-specific part.
If your van is having fueling issues, hard starting, or running rough, a faulty pressure regulator could be the culprit.

This valve controls the pressure in the common rail, and swapping in a new one can smooth things right out.

It's designed for easy installation—just screw it in and connect the plug.

JCM includes a 1-year warranty.

Brand new, ready to go.
If your Merc diesel needs a fuel system refresh, this is a solid, affordable part.
