So I bought a cold enjector delete kit from Hawks . I was wondering if the female nut comes off the fuel rail ? I tried putting a wrench on it and it feels like it doesn't come off , is it locktited on , looks to me like the male bolt in the kit screws into it's place? Doing a speed density 350 swap in a RS any help very appreciative.

Yes it comes out. Bolt it to the intake manifold to help hold it.

Use a 6 point socket to avoid rounding it, etc.

Thanks , yep I gotta go get a 6 point !
