I am assuming this requires a seperate channel just for the dump feature?
I'm as confused as Siclick, what does this system do that a Jettronic valve would not? And.... if onboard propane was a concern, why not just use the tank for starts then disconnect? No knocking your product, just trying to understand the purpose of this unit and justify the cost...

BTW... for those unaware, Jetcat has a nice feature where it will purge the propane during flight if one wishes, just needs to be turned on in the ECU.
