It looks very much like getting fuel to the injector pump is the issue. There's no lift pump so fuel is sucked in. Filter housing was full (from my priming efforts presumably ).Fill that filter housing before replacing to help with the bleeding. If you have had it firing on all four it may help to slacken the connections to the injectors, plenty of rags and turn it over.
just run in at that, those engines have a reputation of going on for a bout ever, I'm sure there are many million mile plus ones. Nothing like the stupidly over-complex nonsense that they make now, where a 100k might be a miricle.This is cheering me up no end (the fuel system diagnosis). Think its 2 but not certain, going to try and pin that down today. 300,000 kms, 37 years young . And special tools needed to pull the injectors of course..
Ta. Looking at the sight glass the priming pump is pulling fuel through from the tank with little effort required but these are all top tips, ta muchlySee if it will run fine and rev up when run straight from a clean container of fuel under the bonnet. One of my favourite tricks for this is to take a rubber hose of suitable size for the fuel intake end in the injector pump, and drill a hole in a 2 litre pop bottle lid that is just a bit less than the outer diameter of the hose, stuffing the hose through the hole. Fill the bottle with diesel and connect hose to injector pump, invert the bottle and secure it higher up than the pump. It'll self bleed and have enough diesel to run the engine even though the pump will be returning a loathe proportion to the proper fuel tank
If it runs nice with this setup, then you're likely looking at a fault of blockages in the fuel delivery system, possibly right the way back to the tank, maybe even crud in the tank. Running a new fuel line (10mm copper pipe) might be faster and easier than clearing the old one, but you could try blasting the lines backwards.
Just bear in mind that fuel tanks often have a small open topped cup inside where the fuel pickup and return sit; it helps keep fuel near the pickup if climbing a steep incline on low fuel level and the majority fuel slips to the back of the tank..
..but it can also help trap crud near the pick-up that is hard to clean out
No, no water in either fuel filter (lot of cr*p though). Think @norseman was right about the noise being due to Easystart- probably detonating.Good news! Were you able to see any water in the filter bowl?
I've found that when these clunker diesels stop because of no fuel, just slackening one of the injector nuts on the cylinder head is enough to start them up.....when cranking, obviously.
If the priming filter needs attention again in the morning, it could be one of the flap valves allowing fuel to return to the tank.
I wonder what the noise was?

Yeah, them's the things. The Merc special tools are quite natty- crows-foot short ring spanner with a 90 degree bend and a half-inch socket drive on top. $22 in the US, a lot more over here!You can get crows foot spanners, ring spanner with a slot cut to pass over the pipe. Worth changing the fuel filter every so often so that its planned rather than breakdown. But glad you have it running, well done.
I have some of them - I never knew they were called that think I have only used one of them once.You can get crows foot spanners, ring spanner with a slot cut to pass over the pipe.
