That makes me nervous because I'm getting ready to fire up my first Saito 100 on a Harrier 90, and the inlet seems to be about an inch below the fuel tank. Don't like the idea of detonating a $300 engine.
First... if 1" of difference were all that important, how could we point our planes nose up? ( where there is MUCH more than a 1" difference ).
Second... how can you "detonate" a $300 engine because of siphoning? The only way I know of, involves utilizing explosives!
ANY engine ( even one properly set up ) can and will "hydro-lock" under some conditions.
It's up to the owner to recognize hydro-lock ( turning the engine over without the ignitor will tell you... ) and NOT use an electric starter when it happens.
That's it, nothing more required.
