How do you explain one injector only out of 6 having black gunk on it?
How does your explanation of hot fuel causing gunk to come out of suspension explain why the injector tips build up, and not the internal filter?
My fuel system has been hot, damn hot many times at the track, and on the dyno, I have never had an issue other than having to re-prime the fuel system to start. Never any rust either. I guess the Hydroscopic nature of the fuel doesn't matter at all seeing it's only in the tank for a month or two in my case, in fact it makes sure there is no water in the tank at all.
Not having a go, but all these misconceptions aren't helping unless you have some kind of proof, as evidence I have seen first hand rules them all out.
