Bunnys(Ardy) tried to get this implemented a few years ago as a mechanical standard in the K4. Research on it showed that it was a murky area of if it actually got updated into many of the K4 rather than it was a field kit. The piping is there but, the hoses have to be cut and valves inserted which then had manual pull noodles from the cockpit. The K4 cockpit photo that most reference was a factory photo to show a finished cockpit with all that could be available. I could never find diagrams for the factory system nor the field kit.
A very wise response from one player. Hitech takes such things into account, then automates them as part of the engine management process he chose to go with.
From all the time bunnys and I spent looking, here is the only photo found that might be the valves. Notice the hose clamps galore, so the references to being issued as a field upgrade are likely.
