Why is my shut off valve not working on my Mercedes?
One of the most annoying problems that the old Mercedes diesels can have, is the shut off valve not working. You turn the key off and the engine keeps running. So out of the car you go and lift the hood to depress the stop lever. That whole operation is a pain, but Mercedes foresaw the valve failing, so they gave you a stop lever to use in a pinch.
Where is the shutoff valve on a gas pump?
There is a small notch in the pump at the bottom of the hole, that mates with the raised portion of the edge of the shutoff valve. Bolt the valve into the pump and then apply vacuum to make sure the arm is pulling on the linkage correctly. Then just reassemble everything back just like you took it off. New valve installed on the pump.

Do you need gaskets for a new shutoff valve?
The new shutoff valve and the 2 gaskets are needed. There is a metal ring that will come off the old valve with a gasket on either side. You will reuse the metal ring, and use the new gaskets. Notice the gaskets have a notch in them as will the metal ring. They fit on the shutoff valve only one way.
