Gravity fed with kero. . Storage tank is well above height of burner some distance away. No tiger loop. When I checked this morning the filter housing as well as nearby isolation valve (supply side of filter) were wet with kerosene, but then I did not know if that was a result of handling when...

Right, well it has cut out again. Gosh. However, this time I am hoping it is an air lock. Like I said, after he fitted the new filter there was an accumulation of kerosene in the plastic container I put down to catch any spills. I emptied that earlier on and when I went back there was a small...

Interesting, thanks.

Ah, pity. Sounds like they have nobbled the enterprising DIYer on that one (maybe with good reason though). I suppose one really shouldn't cut corners with this, so an alternative for me will be to get someone in to do a gas analysis after I have done any work.

I realise this is going off at a tangent, somewhat, but I am fascinated by possible parallels between the boiler set up and a motor diesel injection system. I have a hunch, now, that if you stand behind your diesel vehicle while it is running at idle, and you get a smell from the exhaust which...

Thanks very much for that, John. Yes, the gas analyser is a nuisance. The pressure gauge is no problem, but I don't really want to fork out for an analyser, and then for an annual re-calibration service - on the off-chance I will need it. Would be tempting, though, if one came up secondhand...

Spare nozzle already ordered, and tomorrow morning I am back down the plumbers merchants to get another couple of filters. I am also going to get another burner (same one so I can straight swap if need be) and rig up a supply on a bench, and then play with it until I can strip the bugger down...

Well now, here's a thought: every so often I add stuff to my tank to clean off the injectors, or I use premium diesel to do that same thing, and then shove it into fourth and ramp it down the motorway. Suppose the reason for needing to do that is not changing the fuel filter regularly enough...

Not quite (although I am mightily relieved) - I want to continue with this until I have a thorough understanding of it, so that when it happens again I am not so helplessly dependent.

Well, perhaps there is a period after a filter loses its capacity to perform its function and before it becomes completely blocked. So a 'dirty' filter will reach a point where it allows the medium to flow (perhaps at a reduced rate) but no longer takes out the impurities it was designed to...

Well, I don't think there is any cause for disagreement, because the obvious sign was the burner lockout after the nozzle filter became clogged. It must be the case that a filter reaches a saturation point where it loses its ability to filter out impurities from the medium in which it is...

Yes. I know for a fact that it doesn't stop the flow. In an uncertain world that fact is something I can hang on to, for I have seen it with my own eyes. However, there is this - and it confirms what you just posted - the old pump had seized and was swapped out as part of the repair process. So...

Not so sure about that? The clogged filter was not stopping the oil getting to the burner. The pump was still pulling the oil through to the nozzle - that is how come the nozzle filter was getting clogged. You may have missed the earlier post I made when I said that on each occasion the boiler...

Update, if anyone is still following this. Chap came back to fit new filter and hook it all up and now boiler has been up and running for about 48 hours. Crucially the plume from the vent smells cleaner than it has for years. I really don't want to tempt fate by saying it is all solved...

I'm signing off this thread now. I need to take a chill pill on this and just wait for things to resolve themselves. Thanks to everyone who contributed.

I hope I never see anyone on the tv talking about the need to add bio-fuel to kerosene to save the environment, otherwise I will have to add the cost of a new television to the cost of the boiler repairs. Is say boiler 'repairs'. What I mean is unresolved boiler breakdowns.

Thanks for the additional replies. I still waiting on the guy to respond to my text abut the clogged filter. Nothing. Not a word. I'm so angry now I'm in more danger of being killed by a stroke than than dying of cold, although it feels like it is 50/50. Trouble is, losing it never resolves a...

I will, thanks. And thanks again for the advice, it really has given me hope.

Ok, that's new information. Thanks for that, I will look it up.

Ah, so. Makes perfect sense. So the suction is dragging the oil through the blocked filter and bringing crap with the oil. Well, we shall see if a nice new clean filter sorts the problem. Thanks to your help, and that of others, I have gone put insulation around the exposed copper fuel line...
