Fuel line routing from dual petcocks on Jota 1000

I need some help routing the fuel from the petcocks on a Jota 1000. Right now they both feed directly into the double banjo on their respective sides then jumped to the middle carb. It’s behaving strangely. Admittedly, I’ve never worked on a bike with two petcocks that didn’t first go to an x or y connection first, but I’m not seeing that anywhere. Should I only have one on at a time?

I’m pulling my hair out with this one and I bet it’s something dumb. I can post pics in a bit.
 
Eureka! I knew it would be something dumb.
So the flow was bad but the petcocks are brand new, so I popped the tank lid and it started free flowing. Do these not have a vent in the gas cap? Or does it balance when both are on?

Also after looking into it, I was running 1/4 inch fuel line and it looks like 5/16 is more like stock. (I think 7mm?) so I ordered that.
 
After market taps, like BAP brand don't flow enough fuel. The correct ones are available. Other mod is to ditch the double banjos and set up a fuel rail from the RGS model, which feeds directly to each carb. There is a chance of fuel starvation on the centre carb at WOT with the original setup, ok if you're tooling around.
