I'd love to hear your readily available solution?
I asked this question last year and didn't come up with any simple solutions. CM mentioned his custom built system, but otherwise the consensus is that moving fuel from vehicle to vehicle in modern cars is not simple.

More shameless self promotion, if you don't mind...
Also.. This is only slightly more difficult on a not ancient EFI Ford. You just have to jump the fuel pump relay instead of jump the diagnostic connector. If you really want to see what I'm talking about, this badly needs done on my Blazer since the fuel smells like a fart crapped its pants and it has no such handy EEC IV connector, so I'll have to do it the way probably 99% of guys do. I can probably commit to filming that this weekend and getting it up this coming week. My back isn't awesome right now (hence my radically increased INGO participation as of late) so... we'll see.
