616 617 Diesel Engine Vacuum Operated Fuel Shutoff Valve

Your diesel not shutting off with the key? - then consider this! FITS THE FOLLOWING: all 123, 116, and 126 chassis from 1977-1985. This includes the 240D, 300D, 300CD, 300TD and 300SD. If your diesel engine is showing signs of shutting off very slowly or maybe not at all, it may be time to replace the vacuum fuel shutoff valve located at the rear of the injection pump. You can check its operation with a hand vacuum pump or you can pull the rubber hose off the back for visual inspection. If there is black oil in the hose its time to change the valve (diaphram has started to leak). This new aftermarket unit comes with new gasket for proper installation. It is a tight squeeze to remove it but not a difficult job for the do it yourselfer. You will be amazed at how nice it is having the engine shut right off again right after turning the key off. Comes with illustrated installation instructions.

PLEASE NOTE: If your engine will not shut off the problem may not necessarily be this shutoff valve. You could have a bad vacuum pump or leaks elsewhere in the system. I have two resources to help you troubleshooting this problem properly BEFORE you start purchasing parts.
