If the fuel pump is putting out more than 7 psi, a regulator should be used to keep the fuel pressure within safe limits and avoid the possibility of flooding. Holley's 4-1\/2 to 9psi adjustable bypass style fuel pressure regulator has 3\/8f npt ports, 1 inlet and 2 outlet, complete with mounting bracket, and is for use when a return line is required, preset at 7 psi, not for use with a mechanical fuel pump.\u003c\/p\u003e","brand":"Pro Parts NZ","offers":[{"title":"Default Title","offer_id":46014132551853,"sku":"HLY12-803BP","price":358.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0763\/4819\/4989\/files\/HLY12-803_1a5680d2-e737-4347-b173-607a7a7e5062.jpg?v=1778850124","url":"https:\/\/proparts.co.nz\/products\/regulator-4-1-2-to-9psi-holley-bypass-style","provider":"Pro Parts NZ","version":"1.0","type":"link"}
