Ran out of oil in the middle of summer, I have an old boiler. Am I correct in the way I want to bleed the line?

So I ran out of oil this morning, my own damn fault I didn't even think to check after winter. This boiler is fairly new to me, I've restarted it before but I'm slightly lost on bleeding the line. My thought is to take off that bottom copper tube on the ignition box, as I can't see another line that would carry fuel. I'm honestly slightly worried about deforming it by pushing it horizontal to get flow from it. I can take off some concrete clamps further down the pipe to give it some more flexibility but I'm still nervous. Am I even thinking about this the right way? For reference this boiler is 45+ years old but still runs at 89% efficiency, so I'm hesitant to just junk it, because it may just keep on running. Oil just ran out this morning from a basement oil tank. The outlet with the fuel filter is like 9" off the ground and the inlet to the ignition box is at about 6". Will there be enough pressure to flush air from the line? Thanks for the help! submitted by /u/Blank1268 [link] [comments]
