My cowl flaps were replaced with the mechanical kind.
They work “ok”.
They tend to not lock 100% and sometimes pop open
The cies senders have been amazing and worth the money in my opinion.
I worked with them to reengineer the design (longer and changed orientation)
after too much unuseable fuel with original design.
Here is a link to the gauge i use to display.

The fuel gauge is third from right on top row.
