I did siphon out the fuel and have a look and then put it back while I was in the yard where I bought the boat that looked OK ishOwww
You definitely have lots of crud.
How much fuel is your tank? Is it possible to drain the tank, into another container(s), flush the tank out at least a little, then put the fuel back in from the top and avoid the crud settling in the bottom? This won't eliminate all of it, but should get the worst. Start with a fresh filter and see what comes thru.
Air leaks, yes they come & go. Air will suck thru a leak that diesel fuel will not drip thru. If you have old copper fuel lines, they have probably become brittle with age (like my knees) and good to replace. You can find industrial fuel hose cheaper than marine, made to the same specs (in the same factory), you already know about going to farm stores instead of yachting stores! But if this is part of your problem, it would probably recur more often. That you've made a power run recently with no problem is a good sign.
I think that the initial header tank crud is a different colony of diesel buggery.... possibly more severe than the main tank... the marine 16, three tanks of fresh fuel and a good north sea shaking mean that the fuel in the trap now looks clean.
My optimism about a positive outcome remains undimmed
