I can't believe that was the cause (if that was the cause). I've replaced most of the hoses, and the lift pump, and removed and re-connected all connections, repeatedly... I dread to think how many hours I've spent down in the engine so far this year because of one little bolt!

Meanwhile we had a little excitement recently when HMS Somerset parked next to us in the anchorage. We had a 24/7 armed guard watching us for a few days so I slept sound in the knowledge that if we developed a problem, they'd probably pop round and knock on the door and tell us. We moved away however partly due to the strong wind forecast (which is now upon us and causing us to list violently) and partly due to HMS Somerset's twin Rolls Royce gas turbines which they forgot to turn off at night.
And then we found some little white insects. I'd seem them here and there about the place, but since we got back aboard last week, there were definitely more of them. I asked the Natural History Museum bug identification forum for help and it turns out we had 'book lice' which like warm, damp environments, lots of cracks and crevices and dried foods. Clearly they evolved to like boats then! We found quite a few under our basket we use for bread. I promptly freaked out and felt itchy all the time, so Rose took command and we emptied all kitchen lockers, deep cleaned them - and everything in them and proceeded to throw out absolutely everything we had that wasn't totally sealed up. Then sprayed insecticide liberally and especially in cracks and crannys. Then went out for the day.
Since then we have seen no bugs.
Here's some pictures...
