I just bought a fixer upper 240d, I replaced both the fuel lines on her and I also replaced a third line which I believe has somerthing to do with the pressure release. I bought a new boot that goes the end of that line, but it still leaks bad. Is there something I'm forgetting or is there a valve of some sort in the gas tank I need to replace?

minni,

Your problem is you that you have the wrong tank. You should have a Diesel fuel tank. LOL

Wow P.E., that was incredibly helpful to a person with 3 posts under their belt.

minni, your description doesn't make it clear where the leak is located. In the engine bay, or under the car? This may be difficult if you don't know the terminology for the parts. If possible, post a picture.

Minni,

There is no valve in the fuel tank. There is a fuel strainer in the tank that is connected to the steel fuel line by a rubber hose about 10 inches long. There is also another fuel line. It is a return from to overflow of the injection pump,the injectors and the bleed hole in the fuel filter.

I'm wondering what the 3rd line is you are talking about. There is an overflow line on the top of the fuel tank that goes into into a reservior that acts as an expansion tank.

You should be able to see where the fuel line is getting wet from underneath the car. If its leaking from the engine, check the overflow hoses on the injectors.
