CM2250 Leaking doser

Did a forced regen last night, my tattletale(Rand McNally) said I used 10+ gallons and ran for 114 minutes. I think the actual regen went about 95 minutes and I let it cool to less than 10 deg. difference between the inlet and outlet. It made it to 1200 in and out and was 0.5 inHg diff. It was interesting to watch it walk the inlet up and then wait for the outlet to max out and then do it all over again and again and... I'm not normal.
