    Re: 1979 EGR Vacuum Control Valve

    Here's EGR vacuum relay for a 1978 L48. I believe you have got three issues to consider but I get the impression you're looking for part # confirmation. In addition to part #, consider finish (color-coded) and configuration (what it looks like). I have looked at many of these for 1978-79 by L82 and by L48 with some consistency but also variation by engine RPO...for whatever its worth.

        GM #373510 is the correct EGR vacuum switch for 1978-80 Corvettes. The packaging of the one you picture appears to be about from the late 70's-early 80's period so that would support the possibility that it's configurationally correct. However, I do not know if the part you picture is correct in every nuance of detail with respect to the part originally installed.

        The GM #373510 switch remains available from GM to this very day.

          Here is a service replacement #373510 EGR switch you would get today. I was going to use this but instead stuck with the original. You can compare to an original and will note some variation in the configuration. The bonus photo is a 1929 Ford trimotor passenger aircraft. Saw it overhead lumbering by and had to get a ride in it...DSC03668.jpgthis may not be allowed but each motor (actually engine) had twelve cylinders and did not sport an EGR valve DSC03663.jpg

              Actually, they were nine cylinders - Wright Whirlwinds on early units, Pratt & Whitney Wasps on later units.

                And with those shorty exhaust stacks flying on one of those would have to come with ear plugs.
