With a .150" seat, this needle and seat assembly is about as big as you can get. What's really trick, though, is that the needle is made of titanium! This needle design is very responsive to changes in flow rates and has excellent sealing capabilities.
Features:
- Adjustable
- Titanium needle
- Compatable with racing fuels that contain benzine, acetone and alcohol
