FAQs
What causes fuel injector O-ring failure?
O-rings can fail if they are subjected to too much (or too little) compression caused by a faulty gland design in the car. Other risk factors include improper O-ring installation and inadequate O-ring lubrication.
How many O-rings are on a fuel injector?
Each fuel injector has two O-rings, with twenty-four injectors for every engine.
Can you use Vaseline on fuel injector O-rings?
Vaseline and O-rings are not a good match. O-rings are usually made of rubber, and petroleum-based products like Vaseline can make rubber swell, stretch, and shrink. Mechanics tend to recommend silicone grease instead.
