the replacement electrodes look too short. I bought replacement electrodes for my AFG burner and they appear too short. I took both the old and replacement electrodes apart to see if I could use some of the old pieces to make the replacement electrodes longer, but I could not. I asked the supplier and they say they have been supplying these for years and never hard this before. What an I doing wrong? Before Im told that home novice user should never do this, i did do it once before years ago. I replace these, the nozzle, the strainer, filter, clean out the chamber, replace the gaskets, get it running so it looks about right, then I pay for someone with the gauges and know how to make sure it is running right. the gasket looks different too. tks, pa

I did not opt for any winter additives in our heating oil and it has been very cold here about 10 deg F during the day, -4 at night on the coldest. Our furnace has trouble priming when the tank gets to half full and I was thinking of adding this stuff - is it worth it? I find it hard to believe that 16 oz per 275 gallons will do anything at all. Any insight is appreciated.
