Thermo-Tec 14010 3 ft. 5/8" - 1" I.D. Thermo-Sleeve

This product was easy to install. I used it to insulate my fuel lines. It has not solved my hard-starting when the motor is hot but it performs as I expected.

Just what I needed for a fuel line

Great for insulating Oxygen sensor wiring! I had a O2 sensor plug melt as it rested on the cat. I rerouted the wiring and used this to clean up the look as well as protect the wires from heat.

I used this tubing to insulate the under hood fuel lines in my 1995 Riviera. I have noticed a little more HP since I installed it. I also used it to insulate the coolant sensor and the sensor pigtail.

II have used Thermo-Tec all over my 1940 Ford 2dr coupe. It's a big block Ford powered pro street rod. I've used Thermo-Tec on the headers, mufflers , fuel line and power cables to keep the heat off. This stuff works great.

WRONG SIZE / RETURNED

I put this over my fuel lines on a 67 mustang to keep from vapor locking. Works great!

does the job
