Fuel system theory?
To me its similar to the A&A fuel system but cleaner and less complicated.
Instead of adding an additional feed to the tank for the secondary pump, why not just feed the stock pump into the O44? This would require running a new feed line to the fuel rail, yes. But it would allow the factory system to see the needed psi to switch fuel from the passenger tank to drivers. And this would also allow you to use a FPR at the fuel rail for a return style system. Which I would use the factory feed as the return line. Im sorry if this is all jumbled around(sneaking forum time in at work
)
