Notes
- LB7 Identification (2001-2004): The fuel injector lines on the LB7 are notorious for rusting. We highly recommend replacing your injector lines during installation to prevent fuel system contamination and premature injector failure.
- Supporting Upgrades:
- 50HP – 75HP (20-45% Over): Safe for stock trucks; a Pyrometer is recommended to monitor EGTs.
- 60% Over and Up: Modified or dual CP3 pumps, high-flow lift pumps (200+ GPH), and significant turbocharger upgrades are mandatory.
- Competition Sets (100% – 300% Over): Race use only. Custom tuning and a completed Race Waiver are required before the order can be finalized.
- Final Sale: Once installed, injectors are non-returnable and non-refundable due to sizing errors. Please confirm your power goals with your tuner before purchase.
- Emissions: Not for sale or use in California.
