Guys, I'm about to dive into the turbo install once I get the downpipe back from Trick. When I had the bed up for the hangers, I installed a Walbro 450. So far I have ~2000 trouble free miles on the pump, it's damn near silent too. The turbo will be installed on the stock 145k mileLM7 motor + BTR springs, not sure what kinda power I'll be making... 450-550? I suppose it depends on how high the boost gets cranked? Anyways, I'm planning on running a flex fuel setup, Walbro 450 (obviously), ID1000 injectors, stock lines and stock fuel rails. Will I have any problems with this system or should I bypass the internal filter/ regulator and do a boost referenced regulator in the engine bay and a return line? I do not envision making anything over 600 to the wheels with this truck, the 4L80e is still stock with shift kit/ Circle D. It's a daily driver until things snowball lol

i used 2003 fuel rails (wish had a stock fuel regulator in it) on my 2005 silverado with a 450 walbro, yes it overpowers it a bit but nothing that cant be corrected with the tune, havnt had a problem with it

My 05 has a regulator inside the tank I think?

stock regulator is good for regulating a stock pump and that's IT

I plan on doing the same exact setup on my 2011. I already got the Walbro 450 in it. I'm doing a Holley Hi-ram so I have the Holley fuel rails and I also got the Holley fuel pressure regular and external fuel filter to mount onto the frame. I'll be running a -8an feed line to the fuel rails and I'll be using the stock feed line as the return to the tank. I plan on having the fuel pump hot-wired also.

Who sells fuel rails with the right brackets for the 5.3L intake?
