Works great for insulating the fuel line between the carb and filter. A bit tricky to get it sealing well around tight bends but still doable.

Great product easy to install Other people who used this had issues with the foil tape holding. I used alcohol pad and wiped where the foil tape will be applied. Other people probably didn't do that, You should always clean the area so any kind of tape you use for any kind pf application will stick. Like they say prep is the main part before applying anything.

Used this to thermal insulate the fuel-lines of my '68 Mustang to prevent vapor lock. Worked well, I needed to purchase a second one because the first wasn't long enough. Straightforward and easy to use. I recommend this product.
