I must be living good. The replacement pump fit with no modifications. The input/output nipples were the correct size and the mounting holes lined up perfectly. I need to go buy a lottery ticket. This pump is super quiet compared to the original unit. I will probably see if I can get a pump rebuild kit from Northern. The chemicals are from Do Your Own Pest Control. 1.5 gallon jugs. 1 jug gets me 2 yrs of application
