Vapor Separator Tank

VST Removal

Performing service or maintenance without first disconnecting the battery can cause product damage, personal injury, or death
due to fire, explosion, electrical shock, or unexpected engine starting. Always disconnect the battery cables from the battery
before maintaining, servicing, installing, or removing engine or drive components.
Failure to release pressure from the fuel system will result in fuel spraying out, which can cause a fire or explosion. Allow the
engine to cool completely and release all fuel pressure before servicing any part of the fuel system. Always protect eyes and
skin from pressurized fuel and vapors.
Fuel may still remain in the fuel rails and hoses after draining the vapor separator tank (VST). To avoid a possible fire or explosion,
follow normal precautionary procedures while working with the fuel system. Use a suitable container when draining fuel from
the VST and avoid sparks, smoking, and open flame while in the presence of liquid fuel or fuel vapors.
1. Disconnect both battery cables from the battery.
