efi heater hose routing
I need some help connecting up my EFI conversion heater hoses to my original broncos cooling system. Unfortunately I didn't remove the parts from the donor vehicle (which might be an 88 mkvii) nor was I able to find a cooling system diagram on-line. I'm not familiar which parts of the cooling system is discharge or which may be the suction side. Anyway my intake has two black steel pipes which are intergrated together.The bottom 3/4" pipe screws to front of the intake just behind the water outlet and runs across the to the back. The upper 5/8" pipe feeds the throttle spacer plate. The back of these two pipes I think goes to my heater core? Where do I connect my stock heater control valve to, and does the front of the 5/8 tube go to my water pump?? thanks for any replies..

The pipe that is open at the front of the intake should have a section of hose that goes to the water pump. There should be 2 -1/4" hoses going to the EGR spacer. At the rear, the bottom hose outlet is where I have the heater control valve plumbed into. I used a 90* molded heater hose from the pipe and attached it to a u shaped hose with a 5/8- 5/8" nipple. I attached the water valve there and then hooked up to a regular heater hose that follows the hose from the upper outlet. I tried hooking it up with just the 90* hose, but it put the cable in a bind. You might be able to find a longer cable that would clean it up a little bit. Normally, these hoses are covered by my air cleaner (out of sight, out of mind, I guess ) Eventually, I'm going to be redesigning my dash and I am planning on changing my heater controls over to a vacuum system.
