Forgot to call Edelbrock before cust serv went home for the day - question - is the opening on the left of the performer intake in the rear for coolant? I think the opening on the right (which is on the higher runner) looks like it might be for vacuum. My instructions didn't have any pictures which tells you which port can be used for coolant and which ones for vacuum.

I am assuming that both in the front are for coolant - the right traditionally houses the temp sensor. I want to put the temp sensor in the right, a sensor for the electric fan in the left and I was hoping the opening in the back was also for coolant (that way I don't have to run the heater hose over the nice endurashine intake).

Has anyone else routed their heater return to a different spot?

they are both vacuum in the back, the water passages are blocked off in the rear.

Thanks mystang, I called Edelbrock this morning and they did mention that both were vacuum. Now I have a dilema of how to route the heater hose, I thought there was another inlet port on the back of the engine for coolant but need to do some research.

I am going to send an email to Ron Francis on the wiring kit to see if I need both an electric fan sensor and the temp sensor............

This serpentine setup continues to be "one mod after the next", no doubt it will be very cool once I get it up and running but the Frontrunner system does require quite a bit of mods to work.....
