This is a genuine quality accelerator pump jet designed for several of Weber's popular twin-barrel carburetors. This specific model features dual discharge tubes, meaning it squirts a precise and evenly metered dose of fuel into both carburetor barrels simultaneously upon rapid acceleration.

Having the correct size and a properly functioning accelerator pump jet is absolutely crucial for the engine to respond quickly and cleanly when you press the throttle pedal, without any hesitation or bogging down due to a momentary lean condition. Please note that this model also serves as a direct replacement for older, discontinued original versions of the same type.

Compatible with the following carburetors (among others):

• Weber 38 DGAS / 38 DGES / 38 DGMS / 38 DFAS
• Weber 40 DFI / 40 DFAV
• Weber DCNF
• Weber DIR
