      A:

      Hello No, happy to answer that question for you. This vacuum modulator is not adjustable and would be set to OEM settings. The adjustable units will more for racing and performance applications. We would need vehicle year make and model.

  • Q:

    I have 1975 Lincoln Mark IV, the modulator valve is not hooked in with my carburetor. Is it OK to hook it to the carburetor?

    • A:

      Can be hooked to carb as long as the vacume tap is manifold vacume, NOT Ported (Timed vacume). To test while engine is running vacume port should pull strong vacume at idle and decrease as engine accelerates If the vacume port pulls more vacume as engine speed increases this is ported vacume. DO NOT HOOK TO PORTED VACUME. This will severely affect how your transmission shifts.
