I replaced the black tank in my Jayco. I called Jayco for the correct part number then ordered it through the closest Jayco dealer (who happened to be in CT). It was not a difficult job. My trailer is raised so access was very easy. I also cut the vent and toilet pipes so they could be re-joined with Fernco collars.
