I am leaving next Saturday to pick up my SPF Mark I. I have heard conflicting information regarding fueling the car. I know there is a crossover pipe/line between the two fuel tanks, but is it large enough to equalize the level of gas between the two tanks while filling from a single fill nozzle? Or does the fuel flow in faster than the tanks equalize, in which case I could be spewing gas all over everything while one tank is only partially full?
