Ls swap questions

[Mr. 250r]

Couples of questions, i have tried reading through the huge faq piece and searched the website but could not find everything i needed first off

1. My motor is supposedly an 05 assuming that is correct the power steering has 2 lines coming off of it but the pressure side is also clamp on which i haven't seen should i just run it the same way the return line is clamped on?

2. Is anyone using an ls with the early style 4l80 like mine from 91 with column mounted neutral safety switch, my tranny plug went in fine but obviously the large neutral safety switch plug has nowhere to go

3. There's a plastic line coming out from under the intake cover that goes down behind the heads by the fuel line what exactly is this

4. Can i just use my regular filter, in tank pump setup NOT the corvette setup with my motor which is a return less style setup with a regulator on the rail
