Silly regs. I don't know why not. Maybe they're nervous about having 
a pressurised container of fuel in the engine bay.

Hopefully what will happen will be the same as what happens when the 
float bowl is full on a carbed vehicle, as far as the mechanical pump 
is concerned. The EFI pump will pump the fuel in a loop, so it won't 
pressurise the tank. The regulator should still work OK, since the 
fuel rail pressure should always be higher than the tank/return line 
pressure.

It's a better setup than my plan, but I'm too cheap (and more 
importantly, too lazy) to do it.
