The Holley 121-237 Carburetor Anti-Pullover Nozzle 37 Squirter is an essential performance upgrade for your Holley carburetor. Designed to improve the carburetor's fuel delivery system, this nozzle helps prevent fuel from being sucked into the vacuum secondaries during deceleration, ensuring optimal engine performance.

This nozzle is specifically engineered for Holley 121 series carburetors and comes with a 37 squirter. The squirter is a critical component of the carburetor's fuel system, as it directs fuel from the float bowls to the jets. The 37 squirter is known for providing excellent atomization, which is crucial for proper fuel-air mixture formation.

The anti-pullover design is the highlight of this nozzle. It features a unique venturi shape that helps prevent fuel from being pulled into the vacuum secondaries during deceleration.

By reducing the amount of fuel flowing into the vacuum secondaries, the Holley 121-237 Carburetor Anti-Pullover Nozzle 37 Squirter ensures consistent fuel delivery and stable engine performance.

This nozzle is CNC-machined from high-quality billet aluminum and features a polished finish. Its precision machining guarantees a perfect fit and excellent durability. The nozzle is also easy to install, with a straightforward process that involves removing the factory nozzle and replacing it with the new one.

In summary, the Holley 121-237 Carburetor Anti-Pullover Nozzle 37 Squirter is a must-have for anyone seeking to enhance their Holley carburetor's performance. Its unique anti-pullover design ensures consistent fuel delivery, while the high-quality materials and precise machining guarantee durability and a perfect fit.
