Yes it does,feeds the mechanical pump and splits to both fuel rails. Sent from my SAMSUNG-SM-G920A using Tapatalk

That makes sense, even my dfi mercury outboard has 2 pumps also. Sent from my SAMSUNG-SM-G920A using Tapatalk

It's all good man,just figured you may want to see it. It's a pretty wild setup. But yes there is definitely an electronic primer or helper pump because I here the same thing on my 17. My 15 5.3 did not have this. Sent from my SAMSUNG-SM-G920A using Tapatalk

I think the surging is probably the trans. How new is it..mileage? Fuel injection learning driving habits. Sent from my SAMSUNG-SM-G920A using Tapatalk

Mine does the same thing, I do know the 6.2 has a mechanical pump. It has a roller and runs off the cam. I'm working on the launch of the 6.2 in Spring Hill,Tn. And happened to notice it while delivering parts. Sent from my SAMSUNG-SM-G920A using Tapatalk
