-6 is more than enough for even the mighty ID 2000s.

the perrin fuel rail is set up for the same inner diameter as a -6. Anymore than that is a waste. I run 500 whp on my factory rails and they are -4 equivalent.

I run -8 from fuel pump to distribution block then -6 to each rail and -6 back to the FPR.

yeah, the hoses and nipples aren't, but the fuel lines between the rails and the bends get down to about a -4. That's why I said "equivalent"
