You don't need to. Too bad, I hate to spoil your attempt to sound like you
work for the "agency" !!

I have one of the Orbital injectors for a Mercury Marine DFI 200 outboard
sitting within reach here.

Really, though, it's just too easy to do the same thing with standard parts
and some lathe made bits !

As I recall, Orbital's stuff and patents are intended for use with
DIRECT--not port -- injection.

Different art, as an outhouse lawyer would say.

Besides which--patents don't restrict private, not for profit use of ANY art !!!

(The other side of the intellectual property laws which you and Petie seem
to have so much trouble with!)
