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.

HELP NEEDED WITH CLUTCH PROBLEM!!

Hi there. I have a 300DT Euro with a 4 speed manual. I bought all the clutch related parts to do the job and then decided to have my mechanic do the job.
So we after the installation, all was fine for about 1 week, then the shifting became hard. I took it back and he figured their was some air in the lines still. So he bled the system again, getting a little bit of air out. Then another 2 weeks later, the same thing happened and i took it back again. And now the same thing is happening again.
I don't want to take it back to him again. I trust him and his work, but i would feel wrong in asking him to 'fix it again'. Also, Mercedes are not his specialty, so i am asking for advice from Kent or anyone who has any help to offer.

Black Stuff Blocking Fuel Filters!! 1985 300TD

I have a 1985 300TD converted to run on WVO. It ran great for about a year and then I have been plagued with problems (plugging filters). My oil is liquid gold. I suspected some of the neoprene fuel hose I used was going bad. I drained both tanks ( I have a small diesel tank for starting/purging) and replaced every fuel line and filter. I have been testing the system using diesel only to make sure it all works. I have Kent's little clear filter at the exit of the main (original) tank. It plugs up with what looks like black sand.

1981 300 TD Wagon Transmission doesn't shift

While driving, the trany shifted to nuetral by itself. No position on the gear shift changes the condition. However, when I shift to park I do get a grinding noise before the gears mesh. Every other position is quiet. I was told that I may have to replace the transmission and I am willing to do so as long as a second opinion agrees with the first.

If I do need to replace the transmission, I need a good manual to help out.

85 300CD intermitent starting cylce

My 1985 300cd started acting up today. Car runs great... however today the Car did not start. I insert the key, turn the key to show glow plug lite on, wait for light to go out and then turn key. the key does not turn ( i mean it will not rotate clockwise anymore). Then i will rotate key back to off, pull key out, cycle the transmission from park to low to neutral several times. Then insert key and try again and sometimes it starts and sometimes it does not. Basically i Keep doing this procedure till it starts. After i start the car i drove the car 40 miles with no problems.

1980 300D only shift up to 3rd gear

I just bought a 1980 300d with 200k miles. It looks very well taken care off very clean and even the AC works. The problem is it will only shift the first 3 gears and will not do the last. I've been reading about checking the linkages for the Bowden cable to the transmission and throttle linkage to the injection pump,and vacuum hoses but how exactly do I calibrate or adjust the linkages? They look like they have threads to adjust but where is the right position? How is it adjusted clockwise or counter...Thank you.

1978 300D WVO Cold Startup / Ignition Setup

I just bought my first Mercedes and the previous owner bought and installed the STC 1000. I'm finally filtering WVO and ready to fill it up and was looking over all the documentation/instructions he got from you guys and one thing was a bit
disconcerting ... it says (paraphrasing):

"turn the key to the accessory position before the glow plugs turn on to let the vegetable oil heat up for a certain amount of time depending on temperature and then turning it on to let the glow plugs warm up before starting."

'82 240D Service/Repair Manuals

I just bought a 1982 240D and am struggling with finding a good repair manual. I don't like the CD-ROM manuals that you can find at manualsunlimited.com b/c I like to have the physical manual in hand when I'm doing a repair. I also find the Chilton's manual to be way to general and not very accurate for my '82 240D. I see that mercedessource has a bunch of manuals for sale, that cover a wide variety of 240D related topics. But I don't see one or even two that combined are a comprehensive engine and body repair guide. Can anyone recommend a good service manual (Mercedes Factory manual in print?) or manuals that would cover most major maintenance and repairs? First up for me right now is glow plugs, valve cover gasket, vacuum pump gasket and brake master cylinder.
