To be more clear the motor starts and runs very easily but the fuel tank still hat the Diesel in it from when we bought the car 2 years ago. So I think I should have asked what i need to do about the old diesel.

There is a product called Startron for diesels that will kill anything in the tank and breaks up deposits. That can alleviate having to pull the fuel tank.
If here is a door back inside by the rear window for a first aid kit you can remove that and get at the fuel tank sending unit.
There are hoses and there are steel fuel lines.
If the steel fuel lines are OK there is need to replace them but make sure the rubber isolators on the clamps are functional or a hole can wear into the tubing. Another thing to look for is under the clamps the tubing tends to rust.
If for some reason you want to replace the tubing members have used Conifer brake tubing which is easy to bend without kinking, nylon tubing, and simply used fuel hose for diesels tided in place with zip ties.
There are likely other things used like aluminum tubing or copper (expensive).
If you buy new fuel tubing from Mercedes it comes somewhat rolled up and you have to unbend it.
The fuel outlet from the bottom of the fuel tank has a crimped-on collar. If need to replace that you should drain the tant and you file or grind of the collar metal meatal enough to get the collar off and get the hose off. After that you simply need another clamp and new section of hose to replace the collar.
To pull the fuel tank screen out of the tank you need a 47mm socket or?
