Fuel Injector

The FAST Precision Flow 242 LB/Hr LS3/LS7 profile injectors provide a significant increase in fuel flow over stock while retaining drop-in compatibility for use in GEN III/IV LS manifolds.

• Improved idle quality, throttle response and flow consistency
• Direct install in many EFI manifolds including GM LS3 and LS7 as well as the L76, L92 and L99.
• Compatible with FAST LSXr manifolds when used with appropriate spacer kits
• Special sized O-ring included for drop-in use in GM Gen III and IV LS manifolds
• At 220 lb/hr (@58 PSI, 210 @ 43.5 PSI) the FAST Precision Flow 240 lb/hr Fuel Injectors are some of the highest flowing injectors available.
• E85 & Methanol compatible for use in high-performance EFI applications
• Electrical connectors and pre-assembled pigtails are available for adaptation to other fuel injector harnesses
• Fuel injector spacer kits adapt the Precision Flow 240 lb/hr injectors to other manifold/rail combinations with taller installed heights.
