W110 W111 W112 Sedan, BENZ AID - COMMON QUESTIONS AND ANSWERS

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.

Hi,

I have a '76 240D with an Elsbett conversion kit. Installed right before mercedessource came out with their own kit. Installed the auxillary fuel pump & works great. Also installed an injector line heater wrap. I wish I had gone with the heater Ken offers, didn't know he had it. Another regret, I had someone else install the Auxillary pump and injector wraps and although they work fine, they didn't do as good as a job as I would have, if I had the time to do the work myself. Now I have an Elsbett heat wrap around the the filter, injector line heat wrap and the auxillary pump all pulling juice, works fine but the wiring is getting messy. So three things I'd like to change/correct:

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.

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.
