The Donaldson I used was G082528 housing with P828889 filter, and the Top Spin pre-filter #H002853.Any chance anyone has the part numbers for this Donaldson/Top Spin Setup? I'm about ready to take the copper vitamin trying to clean the Jackson setup and there upgrade doesn't really make changing/cleaning the filter any easier. Thanks, I tried to lookup Donaldson 3" cartridges but it was rough.
