Kendallville-based Flint & Walling Inc. is planning to on-shore some operations. The Journal Gazette in Fort Wayne reports the manufacturer is shifting an engine production line from Mexico to Kendallville's former Superior Essex facility that it acquired a year ago. The publication says F&W is investing more than $5 million into renovations and equipment for small sump pump engines that will be used by its parent company, Louisville-based Zoeller Co.
