A leaking high-pressure line at these cylinders causes fuel loss, misfires, hard starts, and can lead to injector damage if left unaddressed. Replacing them individually saves cost when only specific lines are compromised.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDirect OEM-style replacement for injection lines #1 and #8\u003c\/li\u003e\n\u003cli\u003eRestores proper high-pressure fuel delivery to outer cylinders\u003c\/li\u003e\n\u003cli\u003eEliminates fuel leaks and pressure loss at cylinders #1 and #8\u003c\/li\u003e\n\u003cli\u003eDirect fit for 2001–2004 6.6L Duramax LB7 — no modification required\u003c\/li\u003e\n\u003cli\u003eFrom XDP — a trusted supplier of diesel fuel system components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e2001–2004 GM Silverado\/Sierra 2500\/3500 6.6L Duramax LB7\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eTargeting a specific leak?
