I have a 2001 f150 with the 5.4L V8. Theres a vacuum harness that comes put of the passenger side of the throttle body. Two vacuum lines run across the motor, one goes to my fuel rail pressure regulator an the other goes into the canister on the firewall. Does anyone know what i need to order to fix those two lines. They melted apart an ford is telling me that its part of the throttle body spacer an only comes in a kit for $360.

 

Exactly where did they melt? You may be able to cut out the damaged sections and splice them.
