There is a filter on the end of the pick up pipe inside the tank, undo the pipe before the filter housing and gently blow back to the tank, don't go mad or you may blow the pickup filter off the end of the pickup tube.
Best to do it with a low filled fuel tank and have the bongo level, blow back to the tank then suck back up to prime the pipe.
(Enjoy the taste of diesel.) 🤭.
There is a tank breather at the filler cap and one mounted on the inside of the chassis just in front of the front edge of the tank, push fit on the chassis , look for a black cotton reel sized drum.if you remove this to clean it there is a one way valve inside the breather pipe, a couple of cm up towards the tank, check it's working/clear, these may be blocked with road crud or underseal etc.
