Easy fix.
No drill needed.
Get an AFPR. It has a return line plumbed off the "bottem" of the AFPR.
Hook that up to the stock hard line/return line on the left frame rail.
Remove your stock return lines. Leave the J-tube in place, but not hooked up to anything. (That cover it's attached to? It's the same size as a GM fuel pump cover... so you could replace it pretty easy, just search Summit, and buy one if you want... I removed my pipe, smoothed the plate out, and used it to cover the hole with no tube anymore...perhaps a nice red billet alloy one would be cool, but who cares, and is looking down there anyway?
)
Fuel them comes into your rail, and is pressure regulated and returned to the tank via the stock hard line. No more "secondary regulator" in the J-tube needed.
Easy.
