On my wife's Dakota, the 4.7 had the metal heater hoses/pipes that run from the pump, across the intake and then to the drivers side of the firewall. It's an 04. I bought the truck with a locked up motor, and one of the metal pipes split and cooked the engine. I just bought 5/8 heater hose, and ran from the pump to the firewall. I made to brackets on top of the motor to tie wrap the hoses to, and it works great. I bought a remanned 4.7 from Powertrain Engines, and got a 7 year no fault warranty with it. Very pleased so far. My original plan when I bought it was to swap in a low mile 5.3 LS motor, and a 6L90E. State DMV guy said it would fail the smog test simply because the computer at the inspection station would see the GM ECM in a Dodge...and kick it out!
