Thanks, Si, for your reply.

I was hoping to get a strong smell of diesel around the unions, suggesting a leak in that area, but there was none. Nevertheless, I'll give the area a clean with brake cleaner and go from there.

I've never been able to firmly establish whether the in tank fuel pump is working or not. Would taking a voltage reading at the fuel pump fuse while key in position II tell whether it's working or not?

The fuel filter was last changed in June 2020, 4000 miles ago, with a Purflux C516 packaged in a Volvo box. There is currently just over half a tank of diesel in the tank and the car is parked level.

What are your thoughts on the last video showing the twisting tube to the inlet of the LP/HP pump? That can't be normal, can it?

I can't deny that I might have broken whatever seal might have been between the rubber tube and the LP/HP nipple (there's even a part number for it 30731749!) while taking off the other end. And since it's a pump inlet, there would be suction in that area, no?
