Fuel System problems
I have a 2003 C240. I'm not getting any fuel to the fuel rail. I have replaced the Fuel pump, the filter and the MAF. The car started and did ok it had a little bit of a delay when you stepped on the gas. Other then that it worked pretty good. About a month later the car died out on me. No fuel to the fuel rail.
The only thing I haven replaced at this time is the sending unit on the drivers side. I sure hate to spend $500 if there is no way in heck this could be the problem.
Any ideas?
Oh a side question. There is a hose/pipe that sits behind and to the right of the MAF. What the heck is this? It almost looks like some sort of PCV but I don't think it is.
thanks for any pointers or advice

Glyn,
You were right on the money! I took the fuel pump out and inspected it. I noticed the screen had turned from white to black. I also noticed some deposits. I cleaned the screen, removed the small deposits let the them dry. Reinstalled them and BLAM! The car started right up and took off. A little hesitation when I first step on the gas, but it goes. Oh another observation was the gas in the fuel pump was a dark gray.
Question now is: Any idea on what the deposits were? What could be causing this? I only use premium gas, but I do go to where the cheapest fuel prices are. Maybe bad or low quality gas?
