I know Barry is at the factory at this time. Not sure if any F model K80's will be at Florida.
I know there will be some E models flying for sure.

As far as the flightworks pump it's more efficient and has a little more push than the factory one.
As for the valves they are still using the standards from Kingtech.

I have the standard valves with flightworks pump on my 170 and It runs like a charm every time.

If you are looking for the latest kero start version, contact Barry when he returns I'n a week or send him an email

Take care and happy flying.
