Fuel and vacuum line replacement
Hi All:
First let me say it is great to have the numerous resources to preserve and improve this car.
It's almost overwhelming, the data found online is so mature that pretty much anything that could happen to this car has been documented and debated.
I am in no hurry with my "new" 951, it is comfortably residing in the garage under a brand new covercraft. As one of the first projects, (there's thousands, see I have the right attitude...) I have decided to take the sage advice given on this site and start with plastic and rubber line/hose replacement.
I've seen several kits for vacuum and fuel lines, and would appreciate some comments on the pluses and minuses. I'd like to get as complete a kit as possible in each case.
Are ss braided hoses that much better for a stock 951 engine that won't be flogged?
Lastly, is there any good reason to use different colors of hose on the various individual vacuum systems?
Thanks,
Jim

Fuel lines
I followed the example of http://members.rennlist.com/sharkski...-FuelLines.htm when replacing fuel lines using Gates Barricade (225 psi working pressure) SAE J30R9 3/8" (9.5mm) for the large lines and 5/16" for the smaller return line. Do NOT use SAE J30R7 which is a lower pressure hose but much easier to find. Notice the author of SharkSkin uses fuel injection clamps NOT worm-gear "radiator" clamps.
It is my understanding that the ss braiding is mostly for abrasion resistance or protection and does little to actually strengthen the hose from internal pressure. The braiding does not let one visibly examine the hose for flaws so some people don't prefer it. Many people like the looks of the braiding though.
The thin "hard" plastic vacuum lines on my car were fine but I replaced all the rubber "Y" (I believe it is 928-573-727-02-M200) and rubber elbows (928-574-717-02-M58) from Pelican Parts. Good luck and have fun.
