Why It Matters
A bigger, harder-pulling engine asks for more fuel the instant the throttle opens, and a modest jet leaves it wanting. This 0.50 EMPI pump jet delivers a strong tip-in squirt to a D-Series carb, sized for larger-displacement builds.
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.
Frequently Asked Questions

It meters how much fuel the accelerator pump squirts when you open the throttle, which controls off-idle response. The 0.50 size is one step in EMPI's D-Series pump jet range.
Why does my carbureted VW or 914 stumble when I hit the throttle?
A stumble or bog right as the throttle opens, that clears once the engine is moving, usually points to the pump shot. Changing the pump jet size one step at a time is how that tip-in hole is tuned out.
