I have a 1959 Buick with an 364 engine. I bought a eclectic fuel pump and I am in process to install the pump. I know I should install a oil pressure switch to be safe. My question is where. The old Buick has an Oil pressure gauge that is not electrical. It is a pressure expansion type. I do not want to touch that thing. Is there another place where I can install the oil pressure switch ?? Or is there another way to make the pump stop , I do not mean a on and off switch. Has anyone experienced anything like this or maybe some ideas.
