Default Stock fuel rails

Simple question, will the stock fuel rails be fine on a turbocharged LY6 (6L truck motor) for 700HP? Also what do you guys suggest to use as fuel lines to these stock rails? I am clueless as far as plumbing this thing goes.

With "pump fuel" and a little pressure, most factory hard line is good for 700hp. If your running new lines AN6 is fine for your goals. AN8 (1/2) isn't much more $ though.

Been asked a million times try a search for more info.

Well I recall hearing stuff about the fuel rails being fine flow wise, but mainly I want to know about things such as what connectors plug into the fuel rail (and where to buy them), where I need to plug that regulator looking thing attached to the fuel rail, etc.. This is going into a 78 camaro so I am starting with nothing as far as plumbing goes. When I say clueless I mean it. Not sure how to get useful results from search, all I find is a bunch of big threads about peoples builds and Id have to sift though pages of replies to find that my questions are not answered at all.

You can use an adapter like this: http://www.summitracing.com/parts/fr...2-bl/overview/ to get you from the truck fuel rail connection to an AN fitting. Some people like to use an assembled Nitrous hose that would get you the length of the car (inexpensive alternative), or I've read that Parker push lock is another good option. I simply took the factory truck connectors and cut the "clamp" off of it so I can slide my factory Ford hose over it (with a little heat).

The hose off of the regulator goes to a vacuum source.

And yes this gets covered quite often....
