I am looking for the heavy insulating material (almost like a harness) that is on the fuel line to my carburetor does anyone make this stuff? Photo is attached.

Amazon carries several sizes of asphalt wire loom that may be the same material currently on your car. Here is one size that might be good for the fuel line and they have larger too. YnZ is another vendor although they may have a minimum order amount and there are some ebay vendors that also carry it.

A product with a finer texture that still looks very similar is braided split loom which would be much easier to put on but I don't know if the composition of that material could stand the heat next to the manifold.

Thank you very much.

Summit Racing has a heat shield that is in black and reflects about 60% of the radiant heat from the manifold. It comes in various sizes.
There is also a Velcro option so you don't have to remove the fuel line, and a silver option that reflects about 90% of the radiant heat.

NAPA carries it. I got some earlier this year for my 1941 Clipper. Have not run the engine yet to see how it holds up though.

Those fuel line wraps for the pump to carburetor are probably not needed. This line is pressurized and therefore less prone to heat induced vapor locking.

I believe the practice of using these wraps is a carry over from the days of gravity fed fuel to the carburetor. Keeping the fuel line insulated did help with vapor locking. Also, placing clothes pins on the line to absorb heat was also another trick used back then.

Better to insulate the fuel pump from the engine and carburetor from the manifold.

As John said, but I don't know how effective this was! Although it can hurt anything.

Wood is not heat-conductive so I doubt those are the type of clothespin used ages ago for this sort of thing.

I have seen wooden clothes pins with the Ford logo on them on a Model A. The owner swore they stopped vapor lock. Maybe he was pulling my leg, or really believed they did the job. Go figure...
