Engineered for the 2004.5–2005 GM 2500\/3500 equipped with the 6.6L LLY Duramax, this kit includes all the lines needed to restore proper fuel delivery from the CP3 pump to your injectors — eliminating leaks, cracks, and pressure loss that rob your engine of power and reliability.\u003c\/p\u003e\u003ch3\u003eWhy Replace Your Injection Lines?\u003c\/h3\u003e\u003cp\u003eHigh-pressure fuel lines on the LLY Duramax are subjected to extreme pressure cycles with every start and shutdown. Over time, lines develop micro-cracks, fittings corrode, and connections weaken — leading to fuel leaks, hard starts, rough idle, and loss of rail pressure. A full line replacement is the right call on high-mileage trucks or any time you're doing injector or CP3 work.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eComplete high-pressure injection line kit — all lines included\u003c\/li\u003e\n\u003cli\u003eRestores proper fuel pressure from CP3 pump to injectors\u003c\/li\u003e\n\u003cli\u003eEliminates leaks and pressure loss from worn or cracked OEM lines\u003c\/li\u003e\n\u003cli\u003eDirect fit for 2004.5–2005 LLY Duramax — no modification required\u003c\/li\u003e\n\u003cli\u003eBuilt by XDP, a leading supplier of diesel performance and replacement parts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e2004.5–2005 GM Silverado\/Sierra 2500\/3500 6.6L Duramax LLY\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eWhether you're chasing a fuel leak or doing a full fuel system refresh, this injection line kit gives your LLY a clean, reliable foundation.\u003c\/p\u003e","brand":"XDP","offers":[{"title":"Default Title","offer_id":54611806912804,"sku":"FPE-FL-DMAX-LLY-SET","price":489.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0975\/7202\/8708\/files\/fpe-fl-dmax-lly-set.jpg?v=1781115900","url":"https:\/\/autodieselsystems.com\/products\/045-05-gm-25003500-duramax-lly-high-pressure-injection-line-kit","provider":"Auto Diesel Systems","version":"1.0","type":"link"}
