Review on Enhanced Fire Sleeve and Tape Kit - 1-5/8" I.D. x 3ft - Ideal Heat Protection for Wires, Hoses, and more - Black by Andrew Cramer

WORKS. Used this on my built EJ257 sti. I've had fuel pressure drop issues and never been able to figure it out in my life. I've tried everything in the book except adding an expansion tank. I wrapped 3/8ths of my custom fuel lines in this sleeve as my custom fuel lines were getting hot from my engine and manifolds. Once this was installed my fuel pressure was at a baseline of 45psi. The thing works and works well. My only issue is that the material is difficult to get in the right place because it sticks to everything, but I would buy it again without a doubt.
