Go get us a new gas tank that won't fuel starve too, thanks!

FWIW, I had a really hot-weather track event this weekend at MSR-Houston, and I was pushing the engine really hard. I'm on a 19-row cooler and at the very end of the hottest sessions I'd peak right at 260. That's basically 20-25 minutes of non-stop high-RPM and heavy throttle time. In the space of my single cool-down lap it would drop right back to at least 240, and it'd be back to 220 by the time I reached my spot in the paddock. On the cooler (weather) runs of the weekend, the numbers would drop about 10 degrees.

Not ideal, I really need a 25-row on the hot days around here, but didn't hurt anything either, other than making me want to swap this oil out a little sooner than usual. I just can't imagine what someone would have to do on the street to hit 260 even without an oil cooler, much less 280 (which is the first layer of ECU limp-mode protection).
