Relieving Fuel Pressure

CAUTION: DO NOT SMOKE while working on fuel system. Keep open flames or sparks away from work area. Be sure to relieve fuel pressure while engine is off.
NOTE: Before disconnecting fuel pipes or hoses, release pressure from system by loosening 6 mm service bolt located at top of fuel filter.
  1. Disconnect battery negative cable. Use a box end wrench on the 6 mm service bolt at top of the fuel filter, while holding banjo bolt with another wrench.
  2. Place a rag or shop towel over bolt. Slowly loosen service bolt 1 complete revolution at a time. Always replace washer between service bolt and banjo bolt whenever service bolt is loosened to relieve fuel pressure. Replace all washers whenever bolts are removed to disassemble parts.
