I have two Stewart Warner transducers that look identical. I know one is for oil pressure and the other is for fuel pressure. As I'm looking at them I see on the threaded end that screws to the firewall mounted manifold for pressure transducers that one has a 100 stamped on it and the other a 60 stamped on it. My logic is telling me that the 100 is oil pressure and the 60 is fuel pressure (my engine is injected). Can someone tell me if my assumption is correct or not?
