Safety Instructions

  • Allow vehicle to cool before starting.
  • Disconnect negative battery terminal before starting.
  • For current protection, use a maximum 20-amp fuse.
  • Check or replace oil-pressure safety switch,
  • Support vehicle on stands, not jacks.
  • Keep a Class B/C fire extinguisher nearby.
  • Don't smoke when servicing fuel systems.
  • Ventilate service area; duct exhaust outside.
  • Avoid open flames from matches, lighters, and torches in or near the service area.
  • Use a shielded fluorescent droplight instead of an incandescent bulb; turn off soldering irons.
  • Clean up fuel spills right away; dispose of fuel-soaked rags and absorbent properly.
  • Relieve fuel pressure before opening the system. Otherwise, high-pressure fuel spray might cause a fire or other personal injury.
  • Always replace tank ring seal to prevent leaks.
  • Never use a finger to check fuel injector pattern or pressure. High-pressure fuel can penetrate unbroken skin, causing illness.
  • Never energize fuel injector with fuel line connected except when following OE service manual for procedures and precautions.
  • After working on fuel system, always check for leaks.

Important Safety Precautions!
WARNING: High-pressure fuel systems should be serviced by qualified technicians. Leaking liquid fuel may ignite and fuel vapors may explode, both resulting in personal injury and/or property loss. Read vehicle repair manual for safety precautions, then follow these guidelines to protect yourself and others.
Work Clothing --Wear a long-sleeved shirt, long trousers, and safety shoes. Don't wear a ring or watch that might draw an electric spark. If fuel spills on your clothing, change it right away.
Eye Protection --Wear safety goggles or safety glasses. If fuel splashes into eyes, flush with water first, then go for emergency medical aid.
Fuel Hose --Never use standard low-pressure fuel hose in high-pressure fuel injection systems. Use high-pressure hose marked SAE R-7, or higher.
