What everyone said above! Since you are working on it try to move it and definitely move the fuel line. Then use the heat shielding sleeve material. It comes in different tubing sizes. I used it in my engine bay from the bottoms of the reservoirs (clutch and brake) all the way to their respective cylinders.

Beyond that, another idea might be to try some of the plug wire heat shield sleeves for isolated areas and install it even over the heat shield material. Just a thought.
