Hi,
I have a big green outside oil tank (Home heating etc).
There is a clear thin tube on the outside, with a small floating ball in which is supposed to be indicative of the amount of oil left in the tank. At the bottom of the small tube is a button you press to sync the tube with the tank.
It no longer works and I have no idea how much oil I have without looking in the tank.
Does anyone know how to fix this problem OR is there another method to help me?
Thanks
Paul
