Assemble your hose in hose by first running the 3/4" coolant hose from the tank to where the hose in hose terminates in the engine compartment. You will need two sections of coolant hose that are 17ft long each. slide the 3/8" ID pex fuel line through the coolant line. PEX line needs to be longer then the coolant. Use PB Buster or WD-40 to help the pex slide through the coolant hose.
Run your hose in hose from your tank in the bed along the driver side keeping it close to the firewall and protecting it from abrasions wherever contact occurs
Secure the hose with scrap sections of hose and zip ties. Simply cut a section and split it down the middle. A decent pair of hose cutters will make this go quickly.
Terminate the hose in hose here. I used red 5/8" coolant hose for the hot side and black for the return.
Re route your hot coolant hose coming from the head to the Davco 382 filter. Route the coolant hose coming from the Davco 382 to the stock coolant rail; After you switch the rails and cut the rear bend off of the now passenger side piece of tubing.
After the tubing T in using 5/8" coolant hose. Route 5/8" coolant hose over the valve covers and into the hose in hose tee's.
