  • Fixed my vapor lock issues
Size: 1/2" I.D. Style: 3ft
I used this heat sleeve to cover metal fuel line in my classic car that was having some vapor lock issues. This along with some custom-made shields for the fuel pump seem to fix my issue. Great product and brand-name, would buy again if needed.

  • Good heat shield.
Size: 1/2" I.D. Style: 3ft
I used this on the wires that go to the starter on a 2008 Jeep Wrangler. The insulation on the wire that energizes the starter solenoid had melted even with the factory starter heat shield in place. This Jeep has a design problem because the catalytic converters are very close to the starter. This heat shield work great for this application and solved the problem. ... show more

  • Measure OD of item to be protected before ordering!
Size: 1/2" I.D. Style: 3ft
I ordered this item to wrap the fuel line on my boat. I measure 5/16 ID and figured 1/2" wrap would quite suffice. I should have gotten 3/4 wrap. I had to split, then tie wrap around the hose. Good outcome after applying some ingenuity.
