running braided fuel lines

I know alot of people who run braided lines run them from the rail all the way back to the tank. Is there a reason for this? They connect them to the hard tubes that come from the tank, so whats the difference in connecting the braided line there, or at the hard lines that are in the engine bay? Its seems you would get the same fuel flow either way, with the stock hard line, or the braided line. Not sure this will make sense to people, if needed I will get pics. Just a thought though, seems like a waste of expensive line.

If your running a single turbo setup and plan on running 20+ psi, you should consider running new -6 or -8 fuel lines for a few reasons. The larger lines will carry more volume of fuel. The lines are also very strong and can take much higher fuel pressure than stock lines.

well Im going single I plan on going with braided line, and replacing all the soft stock fuel line. But I assume the hard linea are pretty strong, so when you connect up at the fuel tank, you are still getting the same fuel through those hard lines. Will connecting the braided line there really carry more fuel, then the stock hard line that runs to the engine bay? Also i wont be running 20+psi, I dont think my 60-1 will make 643 hp at any boost

If your going to do it, do it right and not half way. Replace ALL the fuel lines from the fuel tank to the fuel press. reg. to the fuel rails.

What size do you have for your set-up? Also did you replace your factory hard lines (under the car) with a larger size as well?

Im going to be going with -6 lines, but here was my understanding. When most people attach their -6 lines to the fuel tank hard lines, they push the tubing on, and clamp it down like a vaccum hose. So with -6 lines your not really looking at a increase in fuel flow, just a safer, stronger source of tubing. Now why not keep the hard lines that front from the tank to the engine bay, then from the hard lines then run your braided tubing. It just seems the only time you would need to run braided line from the rear of the vehicle to the front, is if you are using something along the lines of a -10.

For power goals <450rwhp stock metal hardlines and hose size are fine, with only the pump and injectors needing upgrades (FPR is debatable). More than that and you probably need 2 pumps, aftermarket rails, aftermarket fpr, and dual feeds into those rails in parallel.

My -6AN supply goes from the fuel pump outlet through a bulk head fitting at the top of the tank, no restrictions here. -6AN return is clamped onto the steel return at the top of the tank.

well im definatly not going for 450hp, and trout Im kinda looking at doing that except attaching the -6 line to the steel feed and return lines that come up in the engine bay. Eventually I would like to run a fuel cell.
