Application Notes:
This kit is intended for use with trucks originally equipped with air-conditioning. If your truck is not equipped with air conditioning, you will need to supply your own 5/8 inch ID hose to run from the firewall ports to the stainless steel heater lines. 
The silicone heater hose (tube to firewall) may require trimming for certain applications or to accommodate modifications made previously to the engine. 
If your truck is equipped with an aftermarket exhaust manifold, the rear heater line standoff will not be utilized and an additional mounting bracket is provided.
