Diesel cloud from under the fuel filter

Hello Chaps.
I am rebuilding the Treg after a crash, the engine is now in, and running, but after the engine has warmed up, a continous diesel smoke is pouring upwards from under the filter housing. I looked after every possible sensor and pipe there, but nothing is leaking. The generator stood in diesel, and engine oil before it was mine, but that mess has been cleaned up. After two hours of running, it still does the thing, small throttle, small cloud, big throttle MASSIVE cloud. The fans are spinning continously, as the AC control is still out of order. The temperature is OK, oil good, servo adequete. Do I have to take the engine out again? Should it be a Tandem pump? Or can it be the residue of the filter house out-in-out-in manuever? The gen is clean, under it there is a slight oil film, but I think it is old.
Thanks guys,

The efirst easy thing to do is to see if there is oil in the charge pipe going into the throttle body thing.
I know it's not a throttle body..

Could be a drippy or open fuel injector.
