Anti-Pulse Valve, for Vacuum Advance Distributors (SVDAs), EACH
Anti-Pulse Valve, for Vacuum Advance Distributors (SVDAs), Each


 

Anti-Pulse Valve, for Vacuum Advance Distributors (SVDAs), Each is used to smooth and strengthen the vacuum advance signal to the distributor, when running IDF or DRLA carburetors. This valve does just that, and works very well! The valve has no resistance one way, and a moderate resistance the other way. This allows the distributor to "see" a full strength vacuum signal, and one that is much steadier than if the valve is not there. You only need 1 of these valves, installed in the vacuum line between the carburetor's vacuum port, and the distributor (Unilite, SVDA, DVDA, etc). The arrow points toward the carburetor(s). Best results are achieved when the Anti Pulse Valve is installed as closely as possible to the carburetor.

Price: $39.95

5 of 5 Anti-pulse valve for SVDA works! December 24, 2013
Reviewer: Christopher Valdivia from Lancaster, CA United States  
Recently installed the anti-pulse valve between the aircooled.net SVDA and the left carb intake manifold (dual 34 carbs) on a 1641 motor in my 73 Karmann Ghia. Not quite gone a hundred miles in this configuration yet but very pleased with the results! Engine running has definitely improved according to my "seat of the pants" instrumentation. Though a little pricey I'm very happy with the improvement in performance!
