Item was as expected. Perfect replacement

### ⭐⭐⭐⭐⭐ Works great for SLL-40
*by A***R on February 27, 2021*

Order was at my door in 2 days and it was installed in less than 20 minutes. My septic air pump is a SLL-40 and this rebuild kit fit it perfectly. My pump is from 2010 and I can only hope that it last another 10 more years
