That looks like the Schrader valve to me, but....what the hell is that screwed up onto it? Some kind of gauge sender??
But I agree with sedanman....sounds pig-rich to me. If it's rich enough to stall when it gets hotter, that car must stink to holy hell. Maybe there's a sensor problem here, like the MAF. Doesnt throw any check engine lights or codes does it?
