Pump Jet EPC DGV 32/36, 0.40

OVERVIEW

Precision tuning is the heartbeat of a well-running air-cooled engine, and nothing ruins a drive faster than a hesitation or "flat spot" when you step on the accelerator. This EMPI 0.40 Pump Jet for EPC and DGV 32/36 progressive style carburetors is the professional solution for fine-tuning your fuel delivery system. When you tip into the throttle, the accelerator pump circuit relies on this jet to deliver a precise, timed squirt of raw fuel into the venturi. This momentary enrichment compensates for the sudden influx of air, ensuring that your Beetle, Karmann Ghia, or Bus pulls away from the stoplight with smooth, linear power. If your current setup feels sluggish or stumbles during transitions, upgrading or replacing your pump jet with this genuine EMPI component is a critical step in restoring drivability.

Crafted to exacting tolerances, this 0.40mm jet is specifically designed for the popular "Progressive" carburetor setups that have become a staple in the VW community for those seeking a balance between fuel economy and performance. Whether you are running a stock 1600cc dual-port or a mild 1776cc street engine, the pump jet size can make or break your engine''s responsiveness. EMPI''s commitment to quality ensures that the internal orifice is perfectly centered and calibrated, preventing the common issues of "dripping" or inconsistent spray patterns found in inferior, generic jets. By choosing the right jet size for your specific vacuum profile and engine displacement, you are investing in the longevity of your engine and the quality of your time behind the wheel.

PRO TIPS

1. Aiming is Everything: When installing your new 0.40 pump jet, it is vital to ensure the nozzle is aimed correctly. The fuel squirt should be directed straight down the throat of the carburetor, ideally hitting the gap between the throttle butterfly and the carburetor wall just as it begins to open. If the stream hits the butterfly plate directly, the fuel will puddle rather than atomize, which can lead to a lingering hesitation despite having the correct jet size installed. Use a pair of needle-nose pliers to very gently nudge the discharge tube if adjustments are necessary.

2. Check Your Pump Diaphragm: A new pump jet can only do its job if it receives fuel pressure from the accelerator pump circuit. If you install this jet and still see no fuel spray when pumping the linkage (with the engine off), your accelerator pump diaphragm may be torn or the check valve may be clogged. Always inspect the rubber diaphragm for cracks or stiffness and ensure the small brass check ball in the bottom of the fuel bowl is moving freely. A fresh jet combined with a healthy diaphragm results in an instant, crisp throttle response.

3. Balancing Size with Climate: While the 0.40 size is a fantastic "all-around" jet for most sea-level applications, environmental factors play a role. If you live in a high-altitude area where the air is thinner, you might find that a 0.40 provides a bit too much fuel, causing a rich stumble. Conversely, in very cold climates, the engine may demand a slightly larger squirt to stay running during the warm-up phase. Always perform your final tuning with the engine at full operating temperature to ensure you aren''t over-compensating for a cold-start condition that should be handled by the choke circuit.
