Is that loose vacuum line the fuel shut-off hose? I assume you are
aware that the way to stop these old diesels is to shut off the fuel.
When you turn off the key, it causes the vacuum solenoid to shut off the
fuel at the injection pump. My vacuum solenoid has been broken for a
while so when I stop the car, I have to pop the hood and push down on
the fuel linkage rod to shut off the fuel. On mine, there is a red label
on a tab that says it is the fuel shutoff. I have the new vacuum
solenoid but have not managed to install it yet.

I was suspicious that the 81 240D had a bad glow plug because it was hard to
start and there was white smoke on start up.
I ordered Bosch glow plugs. they arrived and this afternoon I attempted to put
them in.
I managed to get three of them replaced. however the one which is second from
the firewall was so tight I never could get the old plug removed. I tried all
sorts of tools and even bought a 12 mm deep socket. Unfortunately, everything I
tried ended up almost rounding off the glow plug.
One of the glow plugs was wet. The other two looked okay with typical light
soot.
I also change the fuel filter today. After changing the 3 plugs and the fuel
filter I decided to take it for a test drive around the neighborhood. It ran
fine. I still think the linkage is worn or loose. It doesn’t have much power.
But, when I returned home, it would not shut off. I even tried the stop lever
which seemed to sort of bog it down but it kept running. The only thing I
could think to do was dump the clutch and make it stall. That worked.
So, is this all an indication that the linkage is messed up since it wouldn’t
shut off even with the stop lever? Or did I knock some vacuum line loose
working on the GP.
Any ideas how to get the last glow plug out? There isn’t much room to maneuver
and it is close to rounded off.
