Holley Steel Inlet Needle

Maximize your vehicle’s fuel delivery with this Steel Inlet Needle by Holley. The inlet needle's role is to control the fuel flow in the carburetor’s float chamber. With precise control, the inlet needle acts as a valve that opens and closes to regulate the amount of fuel entering the carburetor’s float bowl. Its steel-tipped design works with exotic racing fuels or alcohol, benzine, and acetone additives. Its robust steel construction ensures it can handle the aggressive properties of these fuels, providing a stable and reliable fuel supply.

Features and Benefits:
- 0.120” Seat Size for 750 CFM Carburetors
- Adjustable Design
- Steel-Tipped Design
- Ideal for Exotic Racing Fuels 
- Compatible with Alcohol, Benzine, and Acetone Additives
- Steel Construction

Its adjustable design allows you to fine-tune the fuel flow to match your specific requirements, especially in high-performance or racing applications where precise air-fuel mixtures are necessary for maximum efficiency and power output. For carburetors with 750 CFM or higher, a 0.120” seat size is recommended. This is because high-performance engines require greater volumes of fuel and a larger seat size allows for increased fuel flow to meet those demands. 

Additional Notes:
- A .097” seat size should be used for small 4-barrel carburetors.
- A .110” seat size should be used for carburetors up to 735 CFM.
