We did a "service hole" and changed the fuel pump for my 110 Td5. It started to leak between the locking ring / seal area and it was opened again (seal looks fine and ring is closed and no other visible leaks such as pipes ect just steady leaking around the ring area that flows on tank surface and drops then) and still it leaks. Any idea what went wrong? Tank must be dropped or new parts ect needed? Thanks!
