VW bug fuel line insulation

[Bluebird]

`72 Super Beetle copper fuel from firewall over intake manifold. What's the best material to insulate this fuel line? It will touch the intake manifold. A split rubber hose or a fabric braided rubber hose, or another insulated material? Thank you all who share mechanical wisdom. Patrick

I've had good luck with DEI wrap on my exhaust pipe, down pipe, and headers (camaro/chevelle)... I have also used their spark plug wire covers with great success. I was going to give their fuel line cover a try on my chevelle but have not yet...

"Scotch 27 Glass Cloth Electrical Tape" might work. It operates at Class B 130°C (266°F). It has thermosetting pressure-sensitive adhesive. I used it to fix a commercial 240VAC electric table-top fryer. When I opened it, the wires and connections were so bad I was surprised it hadn't gone up in flames already.

Made for wiring, but might just work well on a copper fuel line.

Here's another option, https://www.mishimoto.com/heat-defense-reflective-tape-15.html
Vapor lock can be a big problem with fuel lines that run close to a high heat source. Many a small engine had a steel fuel line running next to head and after running for awhile in overly hot weather, would buck and miss then shut down! What pain and not good for a vehicle at all! Sounds like a fun project. Back in the day, had several VW dune buggy type rigs. Was great to be able to swap out a motor with a few nut and bolts, throttle cable and a couple electrical connectors! The fun and crazy times of our youth!

Should a fuel line, Copper, that comes from the Firewall really touch an engine intake that moves around quite a bit? Doesn't sound like German engineering to me.
A picture of the situation would shed some light here.
