There is a temp sending unit that installs in the intake for the fast idle on the TBI. I have a plug on my Edelbrock performer, but the threads are bigger than the sensor. Is there an adaptor that I can screw this sending unit into or do I need to find another one? Also the radiator hose on the top goes right over it, I am going to have to get a straight neck spout for the intake. I did think about disconnecting the heater and using the hole on the other side. Could I just plug the water pump that feeds the heater core and be ok? Thanks for your help.
