I'll check out Aeroquip I need size -4. Don't want to spend an arm and a leg but I am willing to drop a couple hundred if it means cleaning up that mess of black line.
Thanks for the info.

The black lines tend to blend with the firewall and fenders. Also braided lines will get hot, after all they are metal. There is a fine line between enhancing the engine compartment and rice IMHO.
Sorry, just my $0.02.

Personally, I would use fresh black line and route it neatly, using black nylon ties to keep it orderly. Looked good on the old L48. Funny how much of that stuff went away when I installed the 355.

As for the looks, I agree with the others that the black is more subtle and will draw less attention if routed properly. You don't want the vacuum lines to be the thing that pops out when people look at your engine bay.

It's the fluid inside that will make the hose hot or not, on braided or normal the rubber is the main insulator, that said the steel braid can never get hotter than the rubber is on the outside wihtout an external source of heat warming up the braod and because the steel braid is a better conductor it will probably run cooler a sthe braid is a better conductor and has a much larger surface area than the rubber on top of that. What feels colder to the touch, a section of braided hose or plain rubber hose?

A rubber line at 200 degrees is *much* cooler than a 200 degree stainless line. 
Actually, I like the stainless look. There is nothing "rice" about it - "airplanes have been around longer than ricers." On high pressure hoses, the steel will protect the internals and keep the line from collapsing at bends. If color is a problem, they now have black kevlar wrapped hose in addition to the SS.

Oh yeah? a 200 degree rubber line is not cooler than a 200 degree rubber line linered with steel. the only difference is the braid, so if you take off the braid and assume both rubber hoses are the same the rubber surface will be the same temp on the outside for the same fluid temp, then add steel braid to 1 of them, does the braid get hotter than the rubber surface now? If you can make that work you have just had energy jump a medium (rubber) and you should patent the process immediately, it will be a scientific break through.
A 200 degree line is a 200 degree line, (if you want to argue surface temps), 200 degrees is what determines the temperature, not the material, same as a 200 ton pack of feathers is just as heavy as a 200 ton block of steel..

As I recall from some field trip to some science museum a LOOOOONG time ago, different materials at the same temperature will feel hotter/cooler due to the transfer of heat between it and your hand.
Personally, I think braided vacuum hose would look a little too
But, opinions are like a$$holes...

Easy, easy!!!
Note the exaggerated statement followed by the lol emoticon...I was kidding!I also wanted to follow up with my "a pound of feathers is lighter than a pound of steel" quote, but I thought it would be too obvious and you beat me to it.

Well, my engine is anything but subtle but I don't think it's rice either. Maybe old school. All of my hoses came from Summit. They are from Spectra and are not AN hoses but normal SAE sizes with braided covering. The clamps are also from Spectra and are band clamps with covers. The cost for doing the entire engine and all vacuum lines under the hood, including those going to the headlights was probably about $200 if I remember correctly. So far, after being on the car for about 2 years, no problems have occurred and there are no leaks either.
