Fuel Injectors - 65LB/HR (8pk)

The FAST Electronics Fuel Injectors – 65 LB/HR (8-pack) represents a precision-engineered upgrade for LS-series engine builds seeking improved fuel delivery and response. These high-impedance injectors feature EV6/USCAR connectors and LS3/LS7 length specifications, making them direct bolt-in replacements for GM LS engines without custom fabrication or adapter harnesses. The 65 lb/hr flow rate positions these injectors in the sweet spot for naturally aspirated to moderately boosted LS applications, delivering consistent atomization across the full RPM range without the lean-running risks associated with undersized injectors.

High-impedance design ensures compatibility with factory and aftermarket engine control units without requiring external resistor boxes or ECU recalibration for basic operation. The 65 lb/hr rating translates directly to fuel volume—sufficient for sustained power output in street and street-strip applications while maintaining tight fuel distribution across all eight cylinders. OEM-style construction means reliability through repeated heat cycles and long-term ethanol fuel exposure. Eight injectors per pack eliminates the need to source individual units or settle for mixed-age components with varying spray patterns.

This set is engineered for LS1, LS2, LS3, LS6, LS7, and L92/L99 platform engines undergoing carburetor-to-EFI conversion, fuel system upgrades on existing EFI builds, or replacement of aged factory injectors. Builders upgrading to higher-flow injectors or tuning existing LS combinations will find these a reliable, cost-effective choice for maintaining proper fuel delivery and engine longevity. The complete eight-pack approach simplifies installation by ensuring uniform flow rate across the entire engine, eliminating the lean/rich cylinder imbalances that occur when mixing injector sizes or ages.
