I just replaced the factory Rule (since they don't make that one anymore) with an Albins. My concern was I didn't want a autosensing bilge pump, the Albins has a float, and the current stay under the factory 3A, and the Albins 500 is well within that limit and the same volume as the original. Like NESNFRED stated, the mounting holes are the same as the Rule, so you either used short/stubby screws, or glue the strained to the hull.
