OK guys....No more quessing...Sorry if I was a little vague. I wanted to put a pix for this question but could not figure it out. Need some help there. I do not have a web page. Anyway, I stopped by the dealer today and looks like I have an oil pressure switch and an idiot light switch. I believe the idiot light switch was the mystery part. According to the dealer these are mounted on a 2 port fitting which is mounted onto the engine block. The mechanic told me that some jeeps came with the oil pressure gage and idiot light on the dash. I can't figure if I have an idiot light since I have never seen one illuminate before I start the jeep. Could be burned out.
Here is my project....I am going to install an electric fuel pump to prevent mechanical pump vapor lock and a backup pump. The instruction says I need to hook up the electical pump to an oil pressure safety switch. Talked to guys at work and they suggested adding an oil pressure switch, with a tee fitting next to the existing oil pressure switch. This way, if the engine stop the electric pump will stop. My thoughts are I will remove this idiot switch and replace it with another oil pressure switch for the pump. Any thoughts?
