Hello, we have a little problem. We have 2 Burnham boilers with Beckett AFG burners on them and they share a supply line and a return line to the underground fuel tank. The Line does split when going to each of the boilers and the line is a 1/2" I.D. line. The boilers have been running smoothly for about 20 years until about 2 years ago. Now they will sputter and have the flame become completely interupted for a few seconds and then start again. We have gone over the lines and flushed them out and found no visible leaks. These are residential boilers. What could be the cause?
Thank You
