Dead 99' E300TD
99' E300TD just looses power and dies. When it first happened I saw air in fuel lines -looked like engine was starved for fuel.
Rebuilt fuel pump, changed fuel lines, changed all the o-rings, cleaned tank and changed tank filter. Nothing is leaking. Ran for a while beautifully, then died again. Could it be a sensor - diagnostics shows all OK.
Any ideas?

Yes fuel filter o-ring was replaced. Yes there is air in the lines.
A Mercedes mechanic who has the same car and had the same problem. It was driving him nuts because it would be fine for a while and then suddenly die. He finally isolated it to (I'm translating from what he told me in Spanish so this is an approximate description) the primary pump (not the fuel pump). He described the offending bit as a sort of a cam. He rigged up a mini-pump that kept the primary primed full with diesel and that solved his problem. This was a lot cheaper then replacing the primary. So my mechanic spoke to him and is now installing the same set-up.
