Our inventory includes complete and partial spider injector rebuild kits that make it easier to replace worn components without replacing the entire injector assembly. Popular products include:

  • Complete CPI spider injector rebuild kits
  • Injector O-ring and silicone seal kits

Frequently Asked Questions

What is a spider injector rebuild kit?
A spider injector rebuild kit contains replacement components used to restore the performance of a spider fuel injector assembly. Depending on the kit, it may include O-rings, seals, injector tips, fuel lines, retainer clips, or other serviceable parts.
Which vehicles use spider injection systems?
Spider injection systems are commonly found on Chevrolet and GMC vehicles equipped with 4.3L, 5.0L, and 5.7L Vortec engines, particularly models produced during the mid-1990s through the early 2000s.
How do I know if my spider injector needs rebuilding?
Common signs include rough idle, engine misfires, poor fuel economy, hard starting, hesitation during acceleration, fuel leaks, or a noticeable fuel smell.
Can I replace only the seals instead of the complete injector assembly?
In many cases, yes. If the injector body is still in good condition, replacing worn O-rings, seals, or other rebuild components can restore proper operation. Always inspect the entire assembly before deciding which parts to replace.
How do I choose the correct spider injector rebuild kit?
Verify your vehicle's year, make, model, engine size, and OEM part number before ordering. Matching these specifications helps ensure proper fitment.
Does New England Injectors offer individual spider injector parts?
Yes. In addition to complete rebuild kits, New England Injectors offers injector tips, silicone seals, fuel lines, poppet clips, retainer clips, O-rings, and other replacement components.
