{"product_id":"holley-carbureted-bypass-fuel-pressure-regulator-12-803bp","title":"Holley Carbureted Bypass Fuel Pressure Regulator - 12-803BP","description":"Holley fuel pressure regulators are designed to precisely control the fuel pressure from the fuel pump to the carburetor. Too much fuel pressure for a given needle and seat assembly can overload the needle and seat and may cause flooding or drivability problems. Each Holley fuel pressure regulator is fully adjustable so regulating the fuel pressure to your engines needs is a simple task. All Holley regulators are pre-set at the factory so there is no guesswork when first installing the regulator. The Holley 12-803BP fuel pressure regulator features 3\/8\" NPT in\/out ports and a 3\/8\" NPT return port.\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAdjustable fuel regulation from 4-1\/2 to 9 psi\u003c\/li\u003e\n\u003cli\u003ePreset to 7psi\u003c\/li\u003e\n\u003cli\u003e3\/8” NPT ports (1 in, 1 out, 1 bypass or return)\u003c\/li\u003e\n\u003cli\u003eUsed in systems with a return line back to the fuel tank\u003c\/li\u003e\n\u003cli\u003eQuieter fuel pump operation\u003c\/li\u003e\n\u003cli\u003eDesigned only for carburetor use\u003c\/li\u003e\n\u003cli\u003ePolished finish\u003c\/li\u003e\n\u003cli\u003eMounting bracket included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Details:\u003c\/strong\u003e Street\/Strip Carbureted Applications  Two Port Adjustable from 4.5 to 9 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Shiny\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel System:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge Port Included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade Type:\u003c\/strong\u003e Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Gender:\u003c\/strong\u003e Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Port Diameter:\u003c\/strong\u003e 3\/8 IN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Port Quantity:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size:\u003c\/strong\u003e 3\/8 inch NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Type:\u003c\/strong\u003e NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pressure:\u003c\/strong\u003e 9 PS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Pressure:\u003c\/strong\u003e 4.5 PS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Bracket Included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Inline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Gender:\u003c\/strong\u003e Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Port Diameter:\u003c\/strong\u003e 3\/8 IN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Port Quantity:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size:\u003c\/strong\u003e 3\/8 inch NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Type:\u003c\/strong\u003e NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Fuel Pressure Regulator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Quantity:\u003c\/strong\u003e 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range:\u003c\/strong\u003e 4.5-9 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Fuel Pressure Regulator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRebuildable:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReturn Size:\u003c\/strong\u003e 3\/8 inch NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle:\u003c\/strong\u003e Bypass\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Notes:\u003c\/h3\u003e\n\u003cp\u003eThe 803BP is designed for use with an electric fuel pump with a return line in the system.
