Built to OEM specification and matching part numbers 98032549, 8-98032549-0, 095420-0281, 98032549-0 and 095420-0260. Also fits equivalent Nissan models.\u003c\/p\u003e\n\u003ch3\u003eCommon signs of failure\u003c\/h3\u003e\n\u003cp\u003eA failing fuel pressure relief valve typically causes hard cold starting, prolonged cranking, fault code P008A (low pressure fuel system - pressure too low), and on common-rail diesels the engine dropping into limp mode under load. Drivers often notice fuel pressure dropping rapidly after engine shut-off — the valve fails open, bleeding off the rail's residual pressure between starts.\u003c\/p\u003e\n\u003ch3\u003eFitment notes\u003c\/h3\u003e\n\u003cp\u003eDirect-fit replacement, threaded into the fuel rail. Relieve fuel pressure before removal. Apply new sealing washers if supplied and torque carefully — over-tightening can crack the rail. After fitting, cycle the ignition to prime, clear codes and verify the rail holds pressure.\u003c\/p\u003e\n\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\n\u003ch4\u003eIs this the same as the SCV?\u003c\/h4\u003e\n\u003cp\u003eNo — the SCV regulates fuel entering the pump, while the relief valve protects the rail from over-pressure on the outlet side. Both common-rail components but with different functions.\u003c\/p\u003e\n\u003ch4\u003eWhy does my engine start hot but not cold?\u003c\/h4\u003e\n\u003cp\u003eWhen a relief valve fails open, the rail bleeds pressure overnight. Hot starts succeed because warm fuel vapourises and assists ignition; cold starts fail because there's no residual pressure for the first injection cycle.\u003c\/p\u003e\n\u003ch4\u003eWill replacing it fix my P008A code?\u003c\/h4\u003e\n\u003cp\u003eIf the code points specifically to the relief valve, yes. Some vehicles also throw P008A from SCV faults, so confirm with live pressure data before ordering.\u003c\/p\u003e","brand":"PitShopUK","offers":[{"title":"Default Title","offer_id":57283889529176,"sku":"251","price":47.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0947\/3373\/0136\/files\/SKU251_098032549_-9_updated_6915f44e-98b7-45af-9329-c4a60385224d.jpg?v=1781598717","url":"https:\/\/carpartclubs.com\/products\/fuel-rail-pressure-relief-valve-regulator-land-rover-defender-24-2006-onwards","provider":"CarPartClubs","version":"1.0","type":"link"}
