Accelerator Pump Nozzle 0.035

The Accelerator Pump Nozzle 0.035 from Quick Fuel Technology is a precision carburetor component engineered for builders and mechanics seeking reliable fuel delivery during throttle transition. This straight-type discharge nozzle atomizes fuel from the accelerator pump circuit into the carburetor's primary bore, ensuring smooth throttle response and eliminating flat spots during acceleration. Whether you're tuning a street engine, performance rebuild, or vintage carb restoration, this nozzle is essential for matching pump output to engine displacement and fuel demands.

Manufactured from aluminum in natural finish, the 0.035-inch inside diameter orifice is the most common size for small-block and mid-range displacement applications, controlling fuel atomization and metering during cold starts and load transitions. Quick Fuel Technology designs these nozzles to prevent hesitation and stumble by delivering the precise fuel charge the pump is calibrated to supply. The straight discharge orientation allows for optimized nozzle positioning within the bore, critical for proper fuel distribution and carburetor optimization on both Holley and Quick Fuel carburetors.

Technicians and enthusiasts installing or refreshing Holley or Quick Fuel carburetors will find this nozzle indispensable for baseline tuning or restoration work. The 0.035 ID is the standard choice for carburetors on engines between 283 and 406 cubic inches; verify your existing nozzle size or consult carburetor jetting guides to confirm compatibility with your pump volume and engine demand. Installation requires removal of the existing nozzle and simple hand-threading into the pump circuit—a straightforward task that yields immediate improvements in throttle feel and driveability on properly tuned systems.
