Good afternoon all, I was given this Tilley lamp by my mother, was my grandad's before, whilst he was a lighthouse keeper. It seems to be in very good condition, however the tank won't build up pressure. I am 100% confident that the tank is completely sealed, which leads me to think that I have an issue with the pump - I apologise now if any of my terminology is wrong! I bought a new set of seals, but they do seem to be generic, and the one that I think I might need isn't there. I'm not sure what style of lamp it is, or when it actually dates to. It seems that when I'm pumping there is absolutely nothing happening. If I take the pump apart and blow through the outer casing, then air is getting through. The inner part of the pump feels 'loose' and the seal inside the knob part doesn't seem to be doing anything at all. I did fit a new leather 'part' inside the pump, which I soaked overnight in oil. But, it still feels as though no air is being pumped into the tank at all. My gut tells me it's going to be something very simple - to someone that knows about these things - but I have ran out of ideas. I do also need to source a new piece of gauze for inside the stem, as I think the one I removed may have been in there for decades!! Hopefully someone can help. Cheers Kenny PS.
