Yeah, Joe after flying piston powered airplanes for 42 years and owning 7 airplanes, 2 of them with the Lycoming/Bendix fuel injection and having over 4000 hours as a flight instructor, I can imagine that. I agree, it doesn't make any sense. Just an obsevation and probably misguided.

Even 100LL will boil in the injector lines of the Bendix system after shut down and sometimes at idle on hot days. Which is why auto fuel (without ethanol) was approved in some airplanes with carburators, but not for fuel injected systems.

Wellllllllll, excuuuuuuuuuuuuse me.
Then why would you make such an "observation"?
For the benefit of us laymen, use a "sarcastic" smiley face next time.

Re: 66 327/350 idle when hot

This problem appears to be solved. While trouble shooting, the fuel pump finally failed. It has been replaced and the car idles and runs fine no matter what the temp. It has been very hot here the past few days and I have not seen the problem.

The pump was leaking fuel around the interface between the top and bottom. It was not doing that originally when the problem started but after a few days of checking, adjusting and driving it finally went.
