Fuel pump relay potential issues (Page 3/3) A_Lonely_Potato JUL 07, 10:57 PM quote Originally posted by steve308: Now that it's running wrap the wires with a new heat resistant material! I had the wire loom that runs from the relay catch fire! and it resulted in a compromised wire just like you did. Remember that the factiory protective wrap is 30+ years old. I got this from Amazon.....cheap insurance A-Team Performance - Heat Shroud Aluminized Sleeving for Ultimate Heat Shield Protection Barrier with Hook and Loop Closure - 1" x 36" (3ft), 500 degrees F direct and 2000 degrees F radiant heat excellent idea. i wrapped the exposed wiring with some loom and heat resistant tape, but I'll get some of this stuff and do as much of the harness as i can. ounce of prevention!
