Advice on a good regulated return system?
So far I have found the driven kit for 575.00, the sinister kit which also delete the fuel bowl for 700.00 or the riffraff kit for 200.00? Those of you who have experience with any let me know thanks.

If you are wanting to delete the bowl go with the Strictly Diesel kit, if you are keeping the bowl go with the FRx. One isn't better than the other when it comes to the regulated return portion, only difference is the Strictly kit that keeps the fuel bowl comes with larger fuel lines, but you can do that same thing with the FRx and save about $300. I have run both and love the simplicity of the Riffraff kit and that it does the same for under $200.

I put both trucks back to stock. Haven't noticed any ill effects since then.

There are a ton of positive aspects to the factory setup. Simplicity, cost effective maintenance, and about the smallest number of connections possible which equates to fewer leaks in the long run hopefully. The factory setup does return fuel to the tank but only from the fuel bowl and nothing from the heads unless you have really bad injector o-rings.
IIRC, you have an e99. If you go with the SD kit and you still have your factory up pipes then you may as well plan on adding an hour or two to the assembly time because you'll have to remove a considerable amount of metal from the collector on the DS just to get the fitting started in the head....that little tidbit of info is mentioned somewhere in the fine print.
I would talk with Clay at RR to see if the same applies to his FRx.
If you don't have an e99, then this does not apply because on the L99 and up, the collector is located farther away from that fitting.
I think you'll like the FRx and it will be all you will need unless you are wanting to push huge HP numbers. You can have it installed in about two hours on the first try, including a few breaks.
Have you done the Hutch and Harpoon mod?
