This supplement transmits changes that reflect Federal and California standards for gasoline evaporative
emissions that become effective January 1, 2006. Please insert this sheet under the front cover of the manual.
The following items apply in addition to the requirements covered in the Fuel System or Fuel Connections
section of the generator set Installation Manual in which this Supplement is inserted:
1. Flexible Gasoline Hoses: The fuel hoses used inside the generator set meet the Federal and California
standards for gasoline evaporative emissions. The requirements also apply to the gasoline supply hose
between the tank and generator set. Special hose is required to meet these requirements for gasoline
generator sets sold in or used for commerce in the State of California. See your Onan Distributor.
2. Connecting Gasoline Hoses: Lubricants used when connecting fuel hoses can leave residues that can
clog fuel jets. Only use “soap-free” lubricants such as WD40.
CAUTION
When connecting fuel hoses, only use soap-free lubricants such as WD40, which
runs through with the fuel without leaving residues that can clog fuel jets.
