When I first installed the NA FI i routed my fuel feed through a Y block into both fuel rails, then T'd the exit from the fuel rails through my regulator and back to the tank. Since I am re-doing my fuel system for the twins I am wondering if I can run the fuel into one fuel rail, out of that fuel rail into the other and out of that one through the regulator and back to the tank. The whole purpose would be to clean up the installation and be able to route both the feed and return from the rear of engine. What's the consensus on this?

 

That would work perfectly fine. You got it right you want the regulator after the rails then the return line

 

As long as the rails or crossover doesn't limit fuel to the last rail you're fine. Some feed both rails to guarantee equal fuel to both banks.

 

That's how I typically route it.

 

great, so basically I'm good with a one way loop, in one fuel rail out the other. This will make like simple
