fuel delivery prob.
I am having fuel problems on my 300e merc. 1991 I am getting fuel to the distribution center but no fuel to the injectors???? I also noticed that there is clear tube about 1/16th inch inner diameter looks like a vac. hose of some-sort plugged into a vacuum diaphram on the front side of distribution fuel center but not connecting to anything. If anyone could help me with this problem please do so and thank you.

you have k-jetronic (cis-e), yes? If so, make sure you're actually getting fuel to the fuel distributor because of the fuel pump and not because of the pressure accumulator. The accumulator has a spring loaded diaphragm that holds fuel pressure against the injectors when the car is not running. When you check for pressure at the fuel distributor, you will get a least a spurt from the pressure accumulator even with no pressure from the pump. Check the pump back by the pump if you're still not sure. If you really have pressure at the distributor, but not after it, then the distributor may be bad.
