the silver ones don't look as neat but you can easily inspect your rubber fuel lines periodically. yes rubber as it does not file through things and shows is condition on the outside .I do heaps of pressure testing and hydraulics in the petroleum industry with no budget and braided lines are never seen .

what's the purpose of braided lines, anyway? at first i thought it was for fireproofing and heat shielding, but it seems they're not good for either.

Upsides: durable, reliable, great choice for high pressure applications, and big time Bling. Dowsides: heavy, can cut through anything they rub up against, expensive, larger bend radius, more difficult to repair.
Multiply Bling by negative 1 if attached using a hose clamp....;] Bruce

for fuel line applications on the 951;
-abrasion resistance (not necessary, as the lines don't 'rub' against anything)
-durable (the factory stock lines lasted over 175k miles, how much more 'durable' do you really need?)
-reliable (compared to what? the factory stock lines seemed pretty darn reliable)
-high pressure applications (not necessary, the factory stock lines work just as well, if not better)
-don't expand (not necessary)
so as far as fuel line applications are concerned, it would seem the stainless doesn't really provide any benefits over the factory stock.

SS may be a little overkill but so what. Everybody has a different spin on the balance of form and function. Heck, I like seeing the different way people do things. I'm anxious to see what you come up with....Bruce

one big con for the stainless braided line, is that if a leak develops the braids act like a wick and distribute the fuel everywhere, making it impossible to locate where the leak is coming from.

so i've managed to get some fireproof sleeve for the new fuel lines. first, a photo of the stock fuel lines which i've cut out. the top hose is the stock protective 'sleeve' that fits over the return hose. you can see how the left side was melted and damaged by an engine fire that burned for less than 30 seconds. imagine what would have happened if it burned for longer;
next, the new stainless hose with 3000-degree fire sleeve. your engine would melt before this does;
here is a photo of the new stainless hoses installed without the fire sleeve;
and with the fire sleeve. note the end of the center sleeve has not been silicone-taped shut yet, but the other two hoses have. this silicone tape is some good stuff, though a bit pricey;
i've got a bunch left over so if anyone is interested in some identical fire sleeve with silicone tape at $8/foot, send me a PM.

I'll let you know at the beginning of february. I'm replacing the third line and the PO put braded lines on like yours, so I too need to take care of this. I wonder if it isn't worth while to also cover the third line that goes to the damper?
