    This rear jet extension kit is built for Holley and Demon 4150, 4160, and 4500 carburetors with center-hung floats. Under hard acceleration, fuel is pushed to the rear of the float bowl and can uncover the jets, leaning out the mixture; these push-on extensions draw fuel from farther forward in the bowl, and the included notched Nitrophyl float clears the extensions so the float still travels its full range.

    Specifications:

    • Push-on secondary jet extensions
    • Notched Nitrophyl float included
    • Fits Holley / Demon 4150, 4160, and 4500 carburetors with center-hung floats
    • Sold as a kit
    • Part Number: 5896

    FAQ

    What problem does the AED 5896 kit solve?

    Under hard acceleration fuel can be pushed to the rear of the float bowl and uncover the jets, causing a lean condition; these extensions route fuel from farther forward to prevent that.

    What carburetors does it fit?

    Holley and Demon 4150, 4160, and 4500 carburetors with center-hung floats.

    Does the kit include a float?

    Yes, a notched Nitrophyl float is included so it clears the jet extensions.

    How do the extensions attach?

    They are a push-on design onto the existing jets.
