Change carb jets without removing the fuel bowl Designed for center-hung race-style fuel bowls, these kits make changing jets easy. First unscrew the jet plugs, which thread into the bowl, and use the Holley jet tool to remove the old jets. Screw in the new jets, replace the plugs, and you're ready to ride. Available in standard or chrome finish for carb models 4150, 4160 & 4500.
