Got the studs removed & fitted longer ones for deep sump, got a socket for the short stud which is used internally to fix pick-up pipe.
Drilled the hole out in the sump to slight clearance of the socket need to find some pipe now to extend pick-up pipe before fitting sump..
Managed to fit fuel tank in the bus tonight, got 1/4 lights from C&C so will get them built up with seals etc then built up can doors.
