In upgraded fuel systems, the OEM venturi jet pump often becomes a restriction. The Nuke Performance Venturi Jet Pump Unit, AN-6, is designed for modern high-flow fuel systems and features three interchangeable venturi orifices to optimize performance across a wide range of applications.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e1. Feed Line Only\u003c\/strong\u003e - Universal application\u003cbr\u003e\u003cspan\u003eDesigned for applications where the Venturi Jet Pump is driven directly from the feed line. ≈40-45 LPH at 3.0 BAR (44 PSI) differential pressure, or ≈52-58 LPH at 5.0 BAR (73 PSI), is diverted to power the venturi and transfer fuel between tank compartments. This flow loss must be accounted for when sizing the fuel system. Recommended when a return-line-driven installation is not possible or when available return flow is insufficient to drive the venturi efficiently.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2.

When this is not possible due to tank design or installation constraints, the outlet port is fully compatible with the optional Nuke Performance Duckbill Valve, AN-6 (available here). When installed above the fuel level, the Duckbill Valve prevents air from entering the venturi system, helping maintain consistent vacuum generation and reliable fuel transfer performance. Unlike conventional duckbill valves that rely on hose clamps or zip ties, the Nuke Performance Duckbill Valve threads directly into the AN-6 ORB outlet for a secure, leak-free, and service-friendly installation.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Nuke Performance","offers":[{"title":"Default Title","offer_id":50351498920129,"sku":"170-20-101","price":105.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0005\/7773\/2663\/files\/4130-82-170-20-101_01.jpg?v=1782239844","url":"https:\/\/www.urotuning.com\/products\/nuke-performance-venturi-jet-pump-unit-an-6-170-20-101","provider":"UroTuning","version":"1.0","type":"link"}
