Quick Question Regarding Brake lines

Hey guys!
I have searched and searched but am a little confused. I'm getting ready to stick a 6.2 with 6l80e tranny in my '72 burb. It was originally a big block truck so the lines are 1/2" and 3/8" return if I'm not mistaken. I see everyone is running new lines from the fuel tank/ pressure regulator/ pump etc. Is this really necessary? Will the factory hard lines not work? Can't I just change out the rubber hoses with fuel injection hoses and clamps? Am I missing something? My truck has a factory in line fuel filter setup which is where I was planning on putting the Corvette Fuel Pressure regulator. Will the factory hard lines not withstand the pressure of the fuel pump? THanks for the advice guys!!
Shawn

Re: Quick Question Regarding Brake lines

Well the corvette regulator would eliminate the return hard line from the engine bay....so re-using that line won't happen.

You could probably keep the 3/8 line as a feed; the truth is though, by the time you set everything up, it might just be easier to run a new line. Brakeline is cheap, and the insurance of knowing its new on 58+psi of fuel pressure is nice insurance. Its like $12 worth of line.

Also, I have seen aluminum line used on carb fuel applications, and it will blow apart under FI pressure loads.

Re: Quick Question Regarding Brake lines

I am using the stock lines on mine, there is NO reason not to if they're in good condition. I have done this on every LSx conversion I have done and have yet to have a problem.
They are more than up to the task.
