87 300tdt engine full with diesel
 

I tilted the car toward divers side a lot with jacks to make changing the center carry bearing on driveshaft easy. I took my time. Weeks and when done and level tryed to start. The fuel filter was empty and when tryed filling it drained away. To the tank I thought. Filled tank to overfill then poured more in filter till full. Still no start but crankcase full diesel. What happened and how do I fix. Thanks
