I've had a car that I bought second hand have problems because someone previously decided that the in-tank filter was redundant and removed it. This was a VW, but the principle is the same. That filter is to keep big debris out of the lines. If you get a blockage somewhere in the middle of a steel fuel line under the car it's going to be MUCH harder to find and fix. This is experience talking. I did NOT have fun fighting that for a few months. It was hard to track down. It would partially block the fuel, but once it sat for 10 minutes it would then run again. Hard to find when it's working.

Re: [Biofuel] 1980 Mercedes problems
To all who responded to my request for assistance on the Mercedes, My greatest appreciation! Today I expect to get back on it, (the last couple of days were either busy working in the garden, finishing up last winter's stuff, and preparing and planting early spring stuff... then it rained.. and brought water back to both my little creeks!!) I'll keep you posted, and I'll rejoice again when I smell the scent of veggies in the exhaust of this car! Thanks again! doug Jan Warnqvist wrote: Hi Doug, Bill et al. I have some experience from a similar model 300D, five-cylinder engine of 88 hps. My experience of the feed pump is that once there is air in the fuel system is the car impossible to start. But you could try this: There are several bolts on top of the main fuel filter. Loosen the one that holds the connection from the feed pump. Then act according to Doug´s instructions, pump until no air bubbles can be seen in the fuel, then close the bolt and tighten the hand pump. If the car does not start, you may have air in the high pressure side of the fuel system. What helps is to loosen one or two injectors and running the starter, and having somebody to tighten the injectors when only fuel is coming. Even small holes in the fuel tube system may provide a constant flow of air into the system.

Re: [Biofuel] 1980 Mercedes problems
Doug, Probably can't address your question specifically, but can probably provide some links where you can find an answer. First, I changed the glow plugs on my 83 300D, which required disconnecting the fuel lines, which, upon reconnecting required purching air from the lines. To do that had to replace the hand operated pump, which is the only way to remove the air. This could or could not be your problem. But you need to ask the right forum. Here are some links to do that: You wrote: I'm hoping this message is not too far off topic for this list, but I felt this would be the place to look for information from someone else who has been stumped with the same problem I'm facing here.

Re: [Biofuel] 1980 Mercedes problems
HI, am not too sure about the mercedes but most diesel have a ac pump. In my Mitsubishi pajero/montero it is where the diesel filter is mounted. find the pump. then push the top of the pump a few times and then start the car. if it does and subsequently dies off it confirms that the pump has gone to spare parts heaven. if it does not start what you do is pull of the outlet fuel hose from the vaccum pump and pump it manually. if there is no fuel flowing out it suggest the pump has really gone to the spare parts heaven in the sky. what I did with mine was after the two steps above i poured some diesel into the hose i had disconnected using a nozzle and started the car. since the car started it shows there was nothing wrong with the car's engine and fuel pump. To do this I had help to ensure the diesel won't spilled out. Mine happened while it was on the road. Engine died. Poor me. learnt if from my mechanic but my car is a basic model without complicated electronics and therefore easy to trouble shoot. Be careful if you try the above because diesel is at the same time slippery and flamable.
