when i saw how close the oil fire came to melting my fuel lines, i've been worrying about a possible fuel fire in case of another oil fire, or other circumstances.

i've since replaced the fuel lines with stainless, but stainless won't protect your lines against an oil fire as the hose inside will just melt.

thus, i've decided to install fire sleeves over all of the fuel lines. in searching for the best possible fire sleeve, i found insulflex. the problem? minimum purchase is 50 feet !

since we only need about 3 feet, i was wondering if others on here may be interested in splitting this with me. the cost would come up to around $8/foot which is far less than you would pay for lower-grade fire sleeves.

they are only available in red, which i think is appropriate anyway.

I do not understand why we just do not reroute the fuel lines on our cars. Is this a heat shrink type of application(looking at the pics of the fuel line). Aslo would this be a benifit of covering the original fuel lines ?

even if you re-route the fuel lines, they would still have to be inside the engine bay to get to the fuel rail, so they're still in danger in case of a fire.

these are not heat-shrink, they are simply sleeves that are flexible to provide a snug fit.

there would be a benefit of covering the original fuel lines as well, to make them fire proof. these sleeves are good for up to 3000 (three thousand!) degrees fahrenheit.

Hi:

Do you see any benefit if I already have redone all of my fuel lines in AN Style Goodridge Stainless Steel braided? Your thoughts?

I might be interested in jumping in, but that looks more like orange than red....

Look for a local hose supply shop that sells Aeroquip lines and fittings. You may be able to get their firesleeve by the foot without having to buy the entire production run.

I measured the temp on the braided lines and the temperature went up from the stock lines. I added some Thermo sleeve and the temperature when way down. Summit racing sells Thero Sleeve and it looks a lot like the insulflex on the inside and you can buy it in short lengths.

Hey Brian, I am just curious here. What was your base temps before and after? I am interested to know what the braided lines generated temp wise, and if it was taken at idle, after a hard run, etc? What was you criteria for measuring. Thanks.

nize,

Count me good for 5 feet.

That was a couple of years ago so exact number are not floating around anymore. I took the car out for a hard 20 minute run, and then measured the temp on the fuel lines directly above the headers. I replaced the lines with braided line and did the same run, the temperature went up compared to the stock lines. I was surprised at the time but now looking back on it, makes sense. Metal is a very good conductor of heat, you want an insulator on the fuel lines. I then covered the lines with the thermo sleeve, ran the car and measured the temperature inside of the sleeve. The temperature was much lower then on the outside of the stock lines. I guess that is why Porsche put a thick rubber cover on the stock fuel lines.

i have sleeves over my stainless steel lines to prevent abrasion if they rub against each other.

Brian, thanks for the info. That is very interesting indeed. If you have some pics of them, can you please post them? And shaheed, if you have some pics too, do you mind letting us see them?

Thanks.

Here you go.

That's the same thermo sleeving we used on the DP and Cup car. What's nice about it is you can cut it and wrap it around your ball joints if you want, safety wire it (sew) it back together, and it prevents a lot of heat from traveling through the rubber boots on the joints causing them to get brittle and crack. We used this thermal sleave on a lot of stuff.

That is the same type of sleeve I use to cover the fuel line on my race car that goes above the header. The first comment I got from John Millage when I took the hood off my car was very good and pointed to the covered fuel line. The more you can keep heatsoak down on things that don't benifit from heat the better. That is why I am starting to do temp test on my engine components and figure out ways to bring the temp down on those parts.
