It measures fuel pressure from 0 to 145 psi with 1 lb graduation increments, giving technicians precise readings for evaluating injector performance and system integrity. A 2-foot hose connects the gauge to the fuel rail or test port, providing enough reach to route clear of moving components during live-engine testing. This tester is intended for use by automotive service professionals working on fuel-injected gasoline engines.\u003c\/p\u003e\n\u003cp\u003eThe JFP810B is suited for shop use on passenger vehicles and light trucks equipped with port or throttle-body fuel injection. It is appropriate for both initial diagnosis and post-repair verification of fuel pressure. The mechanical gauge design requires no batteries or external power, making it straightforward to deploy at any service bay. Technicians performing fuel system diagnostics, injector cleaning verification, or fuel pump testing will find the 0 to 145 psi range covers the majority of automotive fuel injection applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePressure range of 0 to 145 psi covers a wide range of automotive fuel injection systems\u003c\/li\u003e\n  \u003cli\u003e1 lb graduation for precise pressure readings\u003c\/li\u003e\n  \u003cli\u003e2-foot hose provides routing flexibility during live-engine testing\u003c\/li\u003e\n  \u003cli\u003eMechanical gauge design requires no batteries or power source\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suitable for storage in a standard tool chest\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style diagnostic tool for use on automotive fuel injection systems where fuel rail or service port access is available for pressure testing.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFuel injection pressure testing must be performed by a qualified automotive technician following proper fuel system safety procedures. Before connecting the tester, relieve residual fuel system pressure and ensure the engine is cool to reduce fire and burn risk. Keep the hose clear of hot exhaust components and rotating parts during testing. Always refer to the vehicle manufacturer service documentation for correct test port locations and expected pressure values.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Measuring Range\u003c\/strong\u003e: 0 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measuring Range\u003c\/strong\u003e: 145 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 1 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHose Length\u003c\/strong\u003e: 2 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 16.1 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PROTO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JFP810B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51542945530162,"sku":"JFP810B","price":380.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/127ed58f4fb61435838b49cb7b84e108.jpg?v=1785911875","url":"https:\/\/voomisupply.com\/products\/proto-jfp810b-fuel-injection-tester-0-to-145-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
