Holley HP tumble-polished primary fuel bowl for 4150, 4160, and 4500 type four-barrel and 2300 (4412) type two-barrel carbs. Includes Holley Equipped decal for you to use or not. Clear glass sight window on the passenger side for easy and safe float adjustments. Reduced weight compared to older bowls made from heavier zinc alloy. Excellent sealing with nylon needle and seat gaskets due to non-porous aluminum. Excellent performance, reliability, and safety upgrade for a worn-out float bowl.


This bowl is compatible with vintage Holley carbs (4779) and newer ones (Ultra XP, Quick Fuel Brawler, Slayer, etc.), near any Holley type (many brands) carb with center pivot/hung float. If unsure, send me a message (a photo of your carb will really help).


This listing is for the primary fuel bowl only. Please contact me for custom options. Need screws? Or a pump gasket? Let me know how you want it set up, we can do that! There are other HP bowl listings both with and without accelerator pumps, too.
