Fueling & Injection - Any problem with feeding the front of one rail and the rear of another (pic inside)

I am 99% sure that this wont be a problem, but I am putting together a big fuel system for my ls-coupe and wanted to double check. Basically I am coming through the fender well with a -10 to -8 Y block, going -8 to the rear of the passenger rail and the front of the driver rail, this way I can come from the front of the pass rail to the left side inlet of the regulator and the rear of the drivers to the right side inlet on the reg, then out the bottom back through the fender well.

Here is a rough drawing.

No problem other than added complexity.

why dont you have one feed line, and one crossover tube between the rails, with the regulator and return before the rail?

Why dont you just have a large feed into Y block then from Y to the back of the rails then two lines into a FPR then a return. Less complex IMO

This is exactly how I have it (sans the feeding the rear of both rails).

The current path goes like this:

-12 line from cell to pre-filter/eliminator pump/post filter
-10 from post filter to Y-block under hood.
-8 from y block to rear of passenger rail/front of driver rail
-8 from front of passenger rail/rear of driver rail to regulator
-8 from regulator back to cell

Probably more fuel system then I need, but Aeromotive claims that this setup can support 1,500+hp
