.037in Accelerator Pump Squirters - Tube Type

The .037in Accelerator Pump Squirters – Tube Type from Advanced Engine Design are precision discharge nozzles engineered for Holley carburetor systems. These aluminum components deliver fuel atomization during throttle transitions, ensuring responsive acceleration and crisp engine response when you demand it most. Whether you're tuning a street machine, race car, or classic hot rod, these squirters are essential for carb setup optimization and controlling fuel delivery during off-idle throttle blips.

Manufactured from aluminum in natural finish, these tube-type squirters feature a precisely sized 0.037 inch internal diameter that meters fuel discharge directly into the carburetor bore. The tube design allows for consistent, predictable spray patterns that match OEM and aftermarket Holley carb specifications. Proper squirter sizing is critical—undersized orifices lean out the transition, causing hesitation and flat spots, while oversized nozzles create overly rich conditions. The 0.037in diameter strikes the balance most builders prefer for street applications requiring daily drivability without sacrificing throttle snap.

Carburetor enthusiasts and professional engine builders rely on Advanced Engine Design squirters for consistency and reliability across Holley platform carburetors. Installation is straightforward—these components mount directly into the accelerator pump discharge circuit with no modifications required. Available as a pair, they ensure both pump circuits deliver identical atomization patterns for balanced fuel delivery. Tuners frequently stock multiple orifice sizes to dial in their specific carb setup, making this 0.037in option an indispensable component for anyone serious about carburetor performance.
