About this item

  • 1.Broad Compatibility: This fuel pressure spring is a replacement for TBI 10322 GM,compatible with 1986-1995 2.8L 4.3L 5.0L 5.7L 7.4L TBI motors.Also compatible with Silverado Sierra Suburban Yukon Blazer Camaro Firebird Caprice S10 Jimmy.
  • 2.Pressure bumps from 11-12 Psi to 28-29 Psi: Replacing the original spring with this 28-29 Psi version raises the fuel pressure regulator’s baseline pressure.As a core component, the spring’s increased preload enhances fuel atomization via injectors, optimizing air-fuel mixing for better combustion efficiency and improved throttle response within safe limits.
  • 3.Rated Fuel Pump Necessity: Proper functionality requires a rated fuel pump supporting 28PSI or higher output. The spring’s elevated preload demands sufficient fuel supply to maintain the 28-29 Psi pressure consistently during engine operation, ensuring the fuel system matches the upgraded pressure requirement.
  • 4.Solves Common TBI Problems: It effectively resolves typical TBI issues such as stuck injectors and random fuel delivery shutdowns.By stabilizing fuel pressure at the consistent 28-29 Psi range,the spring eliminates pressure fluctuations that cause performance interruptions,restoring reliable fuel delivery.
  • 5.Core Pressure Regulation Function: As the key part of the fuel pressure regulator, the spring sets the pressure differential between the fuel rail and intake manifold. Its enhanced preload maintains the 28-29 Psi baseline, dynamically adjusting with the regulator’s diaphragm to balance pressure under varying engine loads, ensuring precise fuel control.
