Assuming that you're talking to me, I just bought some blank extrusion and made my own. I have a ModMan intake as opposed to the stock, so I needed to come up with something anyway. For what it's worth I also run them in a parallel flow setup (line from tank splits at firewall into the back of each rail) where each rail terminates at the bypass regulator. Has worked well so far, though I had one freak occurance where the car just died and I never could figure it out. Was just driving home from work and the car started bogging down. Died in the road and pushed it into a parking lot. Could hear the pump prime on key on, but wasn't seeing any pressure at the regulator. Don't know if it just sucked some trash or what, but I just left it and came back in a few hours (had a dentist appointment), and it fired up fine. No issues since.
