Heatshield Products (204011) 3/8" ID x 10' Hot Rod Sleeve Roll

Well made sleeve product. Fit as described. Highly recommend.

Arrived quickly, easy to install and works great

Use 1/2" for a 3/8" fuel hose. Product is well made. I used on custom fuel setup for my Subaru. I honestly don't know if it can handle the heat rating, but engines don't get to 1100 degrees anyways, maybe a turbo or exhaust pipe will. I have done a different Subaru with custom routed fuel lines under the manifold without heatshields and I never had a problem with those. I feel that these will add more security to the hoses. Makes the fuel lines look cool too.*The headshield works like a Chinese finger trap, you need to push from the bottom and the top will loosen up to slide the hose in. Not hard at all once you get the hang of it.

Ran this over a ford small block engine for some oil pressure and temp wires. Works great. Larger sizes I've used around fuel lines for vapor lock issues. Best on the market today!

One layer of this stuff doesn't do much as it's fire proof but not exactly a high efficiency insulator (I tested). I installed as two layers wherever possible, which is difficult on longer runs but easy on short. Be sure to cut it long enough so it doesn't pull back and waste your nice shrink-wrap termination. It only comes with two short pieces of shrink wrap, so be prepared to buy more and it's not inexpensive. Anyway, as two layers it does ok, but it's expensive and stingy on the enclosed shrink wrap so I give it 4 stars instead of 5.

This is high quality stuff, and the size is perfect for the smaller tubes, it stretches a little so you can go to 5/8 and probably 3/4 but I wouldn't stretch it too much or you'll lose the shielding properties. I used it on my fuel lines going from the fuel pump to the carburetor and the under hood fuel line going to the fuel pump. I hope it can help with the vapor locking. I like the heat shrinking end pieces but I don't know if they are better than stainless or plastic zip ties, but I used them and they look nice.

Great product. As other reviews state, get one size larger than the hose you need it for. A 1/2" ID (inner diameter) hose will fit perfectly in the 3/4" heat shield. The heat shrink ends seem kind of thin so I used my own. But the heat shield itself is great quality. It is protecting all the hose in my engine bay very well, even a portion that is right between the block and injection pump.

Very nice tight weave product. Installed easily over brass fittings in fuel lines and appears clean and neat. Supplied with two pieces of manufacture branded heat shrink. For the included length of wrap and cost of kit several pieces of heat shrink would have been very helpful.
