I was able to get mine removed this weekend as part of a scheduled oil change.
I shook out the original fuel that was in it - the hole was small so I am not sure how much I was able to get back in there to rinse out with.
Dried it off, fresh fuel-lube on the threads, back in it went - wired it up and couldn't fly cuz of the weather....

I'll be ordering the spare sender regardless....

Let you know the results of the flight - after it happens!
