Description

Holley needle and seat assemblies can be used as replacements or performance upgrades. Available in different sizes, they're also available in different materials to suit a wide range of applications. Viton® needles are for all gasoline applications, steel needles are used with alcohol or exotic race fuels, and titanium needles are used for their responsiveness during changes in flow rates, as well as for their excellent sealing capabilities. Any way you look at it, you're sure to find the right one for your application.
