Quick question. I'm rebuilding my motorcraft carb. It's time to put the rubber umbrella valve in. What type of grease should be used for this? All I had was lithium grease, wasn't sure so I didn't do it. Thanks in advance.
Sure no problem. This is from the rebuild kit installation notes: "When installing umbrella check valve, coat surface with grease, then carefully push valve through hole in casting until fully seated." This little rubber plug is between the pump diaphragm spring and the body of the carb.
