FAST fuel rails on stock intake? Has anybody adapted FAST fuel rails to stock LS intakes? How did you do it?
Didn't find out until after they were shipped that technically they don't make any rails for anything other than the FAST intake.

I'm not sure what the issue is...I've been running FAST rails on an LS6 intakes for a very long time. The hardest part was finding the right parts to adapt a braided fuel line to the stock hard feed line...other than that, it was bolt on and go.

Can you get me a photo of your rails on your LS6 intake?

That's weird...they have changed the mounting points lately to fit with the new 102mm intake, but that should mimic the current LS3/LS7 intake fuel rail mounting points since that intake was designed to go on the Corvette with those engines.
Here's a picture of the older FAST rails on my stock LS6 intake:

While I no longer have the car, I'll try to help answer your question by asking another question: what are you trying to do? Just run a braided line from the stock hard line to the stock rails? Aftermarket rails?
FWIW, I had to ditch the Earl's stainless braided lines for PTFE lined hoses and fittings due to fuel vapor leeching (my garage would smell really bad after the car had sat inside for only a few hours).

Having the same question. Have an ls3 stock intake, fast lsxr fuel rails from tsp and I'm wondering if I should go buy some rails for a stock manifold or if it will work. Haven't received the rails from tsp yet, so no mock up.
