## Description

Vaccum pump copler sleeve

Review: Worked on Kohler generator - This part broke and my generator and was more readily available than the Kohler part so I took the gamble and fit perfectly. Considering the application of both pieces I expect it to have the same longevity and will definitely order another for backup.
Review: Just and described - Fit my DV-142N perfect and got me up and running.
