I have bought the bosch seals from bongo shop and read the injector pump article but on close observation the leak does not seem to be comming from the dome area it's comming from from the 4 injector pipes area specifically the round {-} screw fuel filter side at the bottom
I undid the fax sheet nuts and diesel came from the dome so did the nuts up again

Any help appreciated photo is take form camera held upside down and used like a mirror under the injector pipes area
