Dont know what the preconceived myth is about the "310's fuel system"
It's not just 310's. It is all Cessna series with tip tanks - 340's, 402's & 421's. And some aircraft have their own peculiar little quirks. I remember an Adelaide based 402B that caught out every pilot that flew it, because you couldn't run on the aux. tanks for as long as the manual said or it would start to cough & splutter!
