That advice might only be valid if the tank had a low level alarm/ trip that would halt the burner function. RTFM if you have one. You could test this by bridging the trip relay and firing the furnace up. Now you have orders the oil, wait and see. PS. Not having such a system myself, I an reasoning by engineering design requirements if I was to build a system like it myself. I don’t know if it would need such a trip, but any “ flame out” situation should shut it down so a trip on low level is a bit OTT. If the extra oil does not help, send me as much info, manual scans piping designs,electrical circuit diagrams and photos and I will try to help. The tank went in early 70s not sure if it would have had an alarm. If it fails to start which it wont as im staying there until it works but I will take more pictures just in case .

I am with Lapourtaider, gravity should mean it will always run and didn't you say the previous owner ran the tank "dry", growing up we lived in an old farmhouse with an equally old oil fired boiler, it was in the cellar and the tank was spring loaded underneath ( a bit like they do with real ale barrels) and it rose when the oil was used and dropped back down when full. My father always explained that gravity was your friend and always to have the tank exit pipe higher than the feed into the boiler. Our oil tank was always running out because no-one thought to check on it in the cellar and we just had it refilled and away it purred again. Surely if you have a pvc tank good to go, put a new feed into the boiler from your new tank and your 26/12 delivery straight into your new tank, if you can raise the pvc tank on blocks to create a good gravity fall. I am not a heating engineer by any stretch of my imagination but the gravity thing works in my head. Im not a qualified heating expert but I do not think it is gravity fed the tank is lower than the boiler.

Before I took it out my 2500L tank was down to 330L and the boiler was still running fine. But of course fuel was already drawn through. I hope his suggestion works. We will know on Wednesday when the tank gets the new fuel.

Dont know if this will help or if you can do it but my nephew is a long time served "Corgi" gas engineer, at a friends house they was having a problem with the old gas boiler, as usual someone had come out and said that it is too old it needs replacing, my nephew checked it over and then got a large hammer and hit the ninety degree flow and return pipes a few times, "Cast iron" the boiler started working, he explained that a 90' corner slows the flow down and over many years bits of crude can accumulate and slow and even block the flow, he then flushed it all out re-filled with "Flowtext"? and its still OK 18yrs later, perhaps you may have a similar problem on the fuel line, but I don't anything about oil burners. I don’t know a great deal about oil burners either. ( Midnight Oil excepted) What I do know it that, unless one has money to burn, one should treat anything anybody trying to flog you anything says with extreme caution.

1000 liters of heating oil for just 1100 euros. Fired up the boiler and no fuel coming through.😃 I'm going for the world record of chucking money away. Next year will return with a pump to empty the old tank into a new above ground one. Failed useless ex wannabe heating engineer should have paid more attention on the ferry.

The house we rent has oil fired c/h and the tank has a clear red line at 500 L. If the tank has been run dry, that could be the cause of your problem.

The heating engineer came up with that theory as well he said the crepanne spelt wrong it's a filter in the tank at the end of the fuel supply line would be clogged up. I removed the two lines from the tank on Monday there was no filter just two identical copper 10mil pipes the previous owner had the same issue I have 😀. Anyway I cleared both pipes fired up the boiler and nothing happened except the feeling of despair. See next post.

I got an email yesterday from someone I'm training up (polar engineer). He said look at JDs thread it could be the diaphragm in the pump I tested him and asked where the pump was. Anyway after technical issues with me he said try two lines of long pipe in a bucket of fuel and if that works it's not the pump so I cut two 6meter lines of copper pipe connected up the fuel filter and switched it on just before it cut out the filter for the first ever half filled with fuel two minutes later when the boiler gives you a second chance I pressed the button fuel filled the filter seconds later the boiler was up and running perfectly. I'm only needing three meter pipe lines as the new tank 20 euros second hand is above ground and in the basement. Polarengineers test proved one of the two underground fuel lines had a leak that is why the pump could not bring any fuel to the boiler. Not the quickest fix in the world but if I had been charging for my time I would have earned a fortune.

The fuel line for the boiler runs through what was years ago part of the vegetable garden. Before me it was where the chickens had access to. In the vain attempt to get rid of liseron/bindweed i had dug down to subsoil - total waste of time, bindweed won hands down.
The only marker that there was a fuel line there was a piece of tubing stuck in the ground.

Master I have an update. I put the tank in place but before I ran the pipework for it I had a brainwave I thought if I cut the flow and return where it goes through the wall and into the under ground tank and run the pipes to the boiler that might just be a quick and easy fix. After a few starts of the boiler nothing so opened up the pipes where it came through the wall and no sign of fuel so mark2 brainwave see below. I noticed the origional pipes were not very far below the ground so I thought take them out blow them out to make sure they are clear and I can use them to run to the new tank. Its the steel pipes with a plastic coating, spent hours plumbing it all in nice and neat, fired up the boiler nothing but after the fifth go at starting the boiler the fuel came through and it ran fine. I sent my OH and said your not going to believe it its working. Checked all the joints and leek free. (that was Saturday) Sunday morning im about to transfer the fuel from the old tank into the new one and I see some water marks on the floor put my finger in the damp area as an idiot does to smell it and yes its diesel but no joints so where the fec was it coming from. The old pipes had tiny little micro style leeks that is why nothing was working it is a very damp basement and they went down in the 70s when the house was built as you can see from the picture they were not 50cm down in the ground. Pulled it all out and will go back up later next week to plumb in the new tank and boiler in but we now know what the issue was I did think about just running new pipes to the underground tank but would hate to waste another day and it did not work and I bought a proper diesel pump to transfer the fuel. 30L per minute it will be for sale soon if you want a pump. Rusty under ground pipes the screw driver gives you an idea on the depth

Fuel transfer completed this afternoon passed by the health and safety expert.

All ended well, heating working with zero issues but there was a couple of hitches. Either last Saturday or Sunday I got everything finished fired up the boiler and withing two to three minutes it twas chucking out toxic fumes from the boiler. I sent Polar E and email and asked him if he had any idea but going by what I was reading of google there was not a good senario. The local CH company opened at 8am on Monday and I went up at 7.30 and begged them to come out, they were there a couple of hours later. He opened up the boiler a clay type brick which was there to protect the back of the boiler had fallen forward probaly when we had moved the boiler and was almost in front of the jet that spits out the fuel. He said right away that will most likely be the problem. He put it back in place cleaned a ton of soot out of the boiler asked if I wanted him to fit a new jet. Yes, I did not care about the price do whatever it needs. So within an hour of him arriving the boiler was running like flippen clockwork. The invoice arrived by email early afternoon 170 euros for everything, I exspected it to cost more. I did give him a 20 euro tip one because the first time he came out he asked who fitted the flexy hoses I said me, he said they are for water not oil and wrote on the bill non conformity. This time he said who fitted the tank and pipe work, I said me he said it was good and did not write non conformity this time.
