If you are still using the petrol fuel filter then that will very likely be your problem. A petrol filter is not designed to flow diesel. I rememeber when Robert's Isuzu powered RR was starving for fuel. He isolated the issue to the same filter. After it was removed the diesel stavation disappeared and the performance jumped measurably.
Mercedes OM617 Powered 110 Build Up
The starting vehicle:
1986 110 with 2.5 liter Petrol engine, leaking fuel tank, and interior and under hood area covered in carpet and other sound deadening material.
Purchased from a UK dealer. It was used by DRA for flight testing of countermeasures equipment. Unique in that it had 44,500 miles and was without front vents presumably to cut down on noise and interference.
