Fuel rail crossover?

[D66stroke]

Is it a good upgrade for a stock truck when used with the blue spring and 6.4 banjo's? I see it opens the back of the heads, but it's only connecting the heads, therefore the fuel would still dead end in a way, right? The truck will always have stock injectors so I thought maybe it would be a cheap upgrade compared to a regulated return.. But what's steering me away is it looks like only 1 company has come up with the idea to make a line for that (dfuser)

Not too many people use a crossover on the 6.0 motor. If your pressures are good there isn't any need for a RR on stock injectors.

I don't have a fuel pressure guage yet, I was just trying to do what I thought would be good for the injectors
