Why It Matters
A lean pump shot shows up as a flat, breathless hitch just as you crack the throttle open. This 0.45 EMPI pump jet (44-1094-0) sets the squirt into a D-Series carb, filling that off-idle hole with the fuel it was missing.
Installation Notes
The pump jet threads into the pump discharge circuit of the D-Series carburetor.
Move one size at a time and road-test between changes to dial out hesitation and bog.
