Bosch Duratherm for a 1980 240D

I bought a Bosch Duratherm glowplug upgrade kit off of Fleabay since Kent was out(same as this one : https://mercedessource.com/node/691)

At any rate, I get the box and on the side it says W123D 08.80- which
to me means from August 1980 on. Well my 240D was born in March
1980. I do have my 1982 parts car in the garage and it does have a
different glow-plug set-up than my 1980.

I could cannibalize the parts car glow-plug setup and transfer it
over to the 1980 recipient car as it will eventually get the 1982 motor
as well.

my 83 turbo diesel stalls after about 25 miles l

I have an 85 300 CD with an 83 engine, my problem is that after about 25 miles the engine starts slowing down and then stalls like it runs out of fuel. let it sit 10 minutes or so and it will start again and run fine for another 25 miles and do the same thing again. will run all day at an idle it only does it at highway speeds. Anyone know what is causing this?

thanks for the help

Air Dam removal

I have a 79' 240D and have been doing the maintenance on the sun roof as per the Mercedessource kit. I have found that the air dam has a bit of rust on it and I wanted to remove it and clean/treat it with the anti-rust paint but I am unsure as to the best way to remove this. I am afraid of breaking it if I force it. Does anyone have any sequence of steps used to properly remove the air dam??? Thanks.

1978 300CD losing power after twenty minutes.

I bought a 1978 300CD with 250K miles about two months ago. So many problems and I've never worked on a diesel but my income is too modest to afford a mechanic. I'm just a humble computer guy. Okay, enough blathering. Recently, the power assist on the brakes gave out and, simultaneously, the car wouldn't shut off when I removed the ignition key. I have been told that I need to rebuild the vacuum pump. After a week of manual braking (that thing's a beast to stop) and manually choking the engine when I get to my destination it's developed a new problem that is far more devious.

1984 300TD Fuel Guage Not Working

I just bought an 84 300TD (Yes, the wagon) and I really like it. One thing that I don't like is that the fuel guage is not working. It jumps all over at times, and at other times it will stay all the way empty (after I just filled it up) or all of the way full. Not sure if this is related, but when I fill it up, I have to put fuel in very very slowly (~.5 gal per minute) otherwise the filler fills with foam and shuts the station pump off.
