Restrictor/Recharge Jet (For square style AC pumps)

This small jet prevents excessive draining of the carburetor fuel chamber when the accelerator pump recharges.  The absence of this recharge jet may cause bogging and stalling during continues throttle fluctuation.  

This jet is ONLY compatible with AC pumps that utilize the smaller "square" diaphragm plunger (See photos)

This jet is inserted into the 1/8" or 7/64" fuel line that feeds the AC pump.
