Don't you think it would be easier for us to help you if we knew what vehicle you're talking about? Click this, read the caption, and fill in your signature:

Well, yes....
In my excitement I neglected that information...
78 F150 (as shown above)
Twin tanks (is that standard?)
460 Auto (400 original according to vinwiz)
4x4

Does this mean this CAN happen? Are the tanks connected? Why oh why?

Well if you do so happen to still be listening, Im not sure for your specific model but in my friend's 1996 f150 the fuel return feeds to the front tank, so if you are running idle in the rear tank you will essentially be pumping fuel from rear to front.
