What can I use to insulate my fuel lines?

Heatshield Products Thermaflect Sleeve is an effective thermal barrier to protect exposed steel and rubber fuel lines in an engine compartment from ambient heat that would cause the fuel inside the lines to reach a high enough temperature to cause vapor lock.

How do I keep my fuel lines cool?

Insulation of the fuel line can help keep the fuel cool. Using a heat-reflective material to wrap the fuel line is one way to keep the fuel temperature down. 4. Heat transfer from an engine block to the fuel pump is a source for raising gas temperature.

What material is used for fuel lines?

More modern vehicles may be fitted with fuel lines made of plastic, typically nylon. Plastic fuel lines do not perish and are lighter than metal tubing, but they melt at lower temperatures and cannot be repaired as easily.

How does fuel line insulation keep fuel lines cool?

Heatshield Products developed our patented FR Fuel Rail Heat Shields™ to create an easy solution to this problem. Our fuel line insulation wraps around the fuel rails to shield them from the radiated heat in the engine compartment.

How do you put insulation on a fuel rail?

First, cut the fuel line insulation to the length of the fuel rail. Cutting and trimming are easy; you can use a pair of regular heavy scissors. When measuring and marking for all the openings, however, don’t forget about a hole for the fuel rail mounting tabs to pass through.

How does heat shield sleeve protect fuel lines?

Our heat shield sleeves have a built-in, high-temp hook-and-loop fastener system which prevents needing to remove fuel lines and makes installation a breeze. A roll of Thermaflect Sleeve can be cut to various lengths, so different sections of fuel lines can easily be protected.

Why are fuel lines protected from vapor lock?

Not only do these sleeves prevent vapor lock, but they also protect the engine lines themselves from heat damage. Even if they’re aluminum, fuel injector rails can soak in ambient heat and transfer that heat to the fuel running through them, potentially causing a vapor lock problem.
