It’s built for custom EFI swap projects—not a universal bolt-on solution—so confirm system pressure needs, hose sizes and plumbing layout before installation. The package includes adapters for common inlet, outlet and return fittings and comes with a one-year limited warranty.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this kit supply the steady 58 PSI my LS swap needs?\u003c\/h3\u003e\n\n\u003cp\u003eThe included filter-regulator is pre-set to maintain 58 PSI at the returnless rail and routes surplus fuel back to the tank, protecting injectors from pressure swings.
