My '84 Mercedes 300D Turbo diesel has become incredibly sluggish since i changed

My '84 300D Turbo diesel has become incredibly sluggish since i changed the bigger round fuel filter. I didnt fill it with gas like advised unforch but screwed it on and just figured i could pump it and it would be fine. im not even sure if thats why its acting the way it is...but its getting worse and seems to be having trouble changing gears. very high rpms. maybe something wrong with the transmission... sometimes i hit the gas and it stalls a second and then jumps forward possibly related....theres a small hose that keeps coming separated in the top right area under the hood...to the right of the red stop button

That sounds like the fuel return hose on one of your fuel injectors. You should get about 2 ft of hose and replace all of them including the one in back that is capped and the one to the injector pump. Im guessing when this happens there is fuel everywhere?

It took Mercon Dextron III.

Of course, MD IV, V or Mutli-Vehicle would be better (the new multi-vehicle formula is what is being widely recommended by all nowadays).

their is no fuse for the fuel pump,its a mechanical pump inside the injector pump ,you have a fuel line broke or the rubber primer bulb thingy has split ,if you bleed it out and it still wont start then check out the stop switch on the injector pump but you will find it has a antitheft shroud around it so you can only check for a feed to this but you cant get access without removing the injector pump .

check primary fuel filter for diesel.If none take hose and blow back to tank.You should hear air bubbling. then try letting pump pick up fuel.You could have a clogged screen in the tank.

Can you tell me the oil capacity of the 5 cylinder inline engine.


I presume you have the 300D diesel. If this is the case, you will need 6 quarts for non-turbo, and 8 quarts for the turbo 300DT. Both include a filter change.
