The Holley 37-915 Performance Carburetor Trick Kit is a must-have accessory for any serious hot rod or muscle car enthusiast seeking to optimize the fuel delivery system of their Holley 4150 or 4160 series carburetor. This Trick Kit, designed by Holley Performance Products, is engineered to provide superior idling, quicker throttle response, and smoother engine operation.

1. Holley Secondary Venturi Kit: This kit features a set of secondary venturis with smaller bores and taller stacks. These modifications increase the velocity of the secondary fuel mixture entering the throttle bodies, which results in a denser air-fuel mixture for more power and better idle quality.

3. Holley Accelerator Pump Kit: This kit includes a high-performance accelerator pump that delivers more fuel to the engine during quick acceleration, providing better throttle response and improved driveability.

4. Holley Fuel Pressure Regulator: The Fuel Pressure Regulator is a crucial component of the Trick Kit. It maintains a consistent fuel pressure, ensuring proper fuel delivery to the carburetor. This regulator comes with a 6AN inlet and outlet, allowing for easy installation and compatibility with various fuel systems.

5. Holley 6AN Fuel Line Kit: This kit includes 6AN fuel lines, which provide a secure and leak-free connection between the fuel regulator and the carburetor. The 6AN lines are also more resistant to fuel deterioration compared to traditional rubber fuel lines.
