Description
Fuel starvation during hard acceleration can cost you consistency on the track and reliability in the shop. These Moroso jet extensions reposition your fuel jets deeper into the bowl, maintaining steady fuel delivery under high-performance demands. Whether you’re tuning a drag car or a street-strip cruiser, they’re an essential modification for Holley carburetors running aggressive jetting.
Installation is straightforward on compatible Holley carbs—just thread them in where your standard jets sit. The brass construction resists corrosion and handles fuel’s chemical action over time. You’ll get a matched pair, so you can extend both primary and secondary circuits simultaneously for balanced tuning.
