Need a Fuel Tank Selector Valve

[rajincajintj]

can i ask a stupid question....

how bad would a couple t fittings be? what are my issues with tieing the 2 tanks' lines together? i assume that they would draw and return from both tanks and i would get a huge range increase while i hunt for the right valve.

only issues i see are the returns and at low levels, i think it would pull air out of the lower tank before it would pull fuel out of the fuller tank, right? so i would have to fill up as soon as one got too low, right? i would also have to fill the tanks at almost the exact same time, every time, right?

im not sure its worth the hassle, but i'm just throwing out ideas
