The WnSEu MSCRP C5 Corvette regulator is built to maintain a firm 58 PSI system pressure, support up to 255 liters per hour flow, and accommodate engines in the 550–600 HP range. It directly fits or cross-references part numbers like GF822, 10299146, 19239926, and 33737, and is compatible with many intake configurations including TBSS, NNBS and L92.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this regulator improve fuel delivery on an LS swap?\u003c\/h3\u003e\n\u003cp\u003eThe regulator maintains a consistent 58 PSI reference pressure so the fuel system can deliver predictable injector performance under load. That reduces fuel pressure fluctuation and helps your ECU tune more reliably across rpm ranges.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eConstant 58 PSI base pressure for stable fueling\u003c\/li\u003e\n  \u003cli\u003eMaximum 255 LPH flow to match higher-demand injectors\u003c\/li\u003e\n  \u003cli\u003eSupports power levels typically seen with 550–600 HP builds\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich engines and setups is this compatible with?\u003c\/h3\u003e\n\u003cp\u003eIt’s tailored for GM LS-family swaps and return-style fuel systems but works with many modern LS intakes and returnless designs where an external regulator is required.

The WnSEu MSCRP C5 Corvette 58 PSI fuel pressure regulator is aimed at DIY and professional builders performing LS swaps, high-output naturally aspirated or forced-induction conversions who need a reliable, high-flow regulator. It’s well suited for street\/track cars upgrading to larger injectors and pumps, or for anyone replacing OEM regulators with a higher, fixed pressure reference for consistent EFI performance. Before purchase, confirm your intake configuration, part-number compatibility, and that your fuel pump can meet system flow and pressure requirements.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can this regulator handle boosted applications?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — it supports up to 255 LPH flow and is suitable for many boosted builds up to about 550–600 HP with proper pump and injector selection.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this fit my LS swap intake?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It fits many LS intakes including TBSS, NNBS and L92; verify part cross-references (GF822, 10299146, 19239926, 33737) for exact compatibility.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"WnSEu","offers":[{"title":"Default Title","offer_id":48085542076574,"sku":"B093H7DSV5","price":40.69,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/wnseu-mscrp-c5-corvette-front-view.jpg?v=1785872291","url":"https:\/\/northtrailauto.ca\/products\/wnseu-mscrp-c5-corvette-fuel-pressure-regulator-58-psi-255-lph-flow-for-ls-swap-550-600-hp","provider":"North Trail Auto","version":"1.0","type":"link"}
