SERIES 60 FUEL PRESSURE GAGES FOR THE SERIES 60G ENGINE WITH A HIGH PRESSURE FUEL SYSTEM

Fuel pressure gages should be installed on both high and low pressure sides of fuel system. The high pressure gage should have a range of 0 - 4000 PSI mounted between the tank and 1st stage regulator. The low pressure gage should have a range of 0 - 200 PSI. ‪

Replacement of Fuel Pressure Gages for the Series 60G Engine

Detroit Diesel does not service the fuel pressure gages. Refer to OEM to replace as necessary. ‪

Removal of Fuel Pressure Gages for the Series 60G Engine

Prior to removal or replacement of fuel system pressure gages, the fuel system must be vented. Refer to section and refer to section . ‪

EXPLOSION

To avoid injury from the explosion of natural gas, the engine must be kept in a well ventilated area away from open flames, sparks, and electrical resistance (heating) coils.

Refer to OEM for removal procedure for the fuel pressure gages. ‪

Inspection of Fuel Pressure Gages for the Series 60G Engine

Refer to OEM for inspection procedure for the fuel pressure gages. ‪

Installation of Fuel Pressure Gages for the Series 60G Engine

Refer to OEM for installation procedure for the fuel pressure gages. ‪

EXPLOSION

To avoid injury from an explosion of natural gas, the following precautions must be taken:

  • Do not smoke when installing or servicing the engine or fuel system.
  • Installation or servicing of natural gas equipment must only be conducted in well ventilated, natural gas-compatible areas. Do not install or service equipment in an enclosed area where ignition sources are present without first ensuring that an undetected gas leak may be safely vented without being ignited.
  • Bleed natural gas lines before installing or servicing any component connected to the fuel lines.
  • Natural gas fuel systems are pressurized. Relieve pressure from any fuel system component prior to installation or service of that component.
  • Use a combustible-gas detector. Liquefied natural gas (LNG) is odorless and cannot be detected by smell. Compressed Natural gas (CNG) may be odorless and may not be detected by smell.
  • Equipment fuel systems are the responsibility of the Original Equipment Manufacturer (OEM). Equipment fuel system guidelines must be closely adhered to when installing or servicing equipment. Refer to OEM guidelines specifying which maintenance procedures require venting of fuel lines and fuel tanks.
  • LNG systems are pressurized and contain extremely cold (-260 F [-162 C]) fluids. Contact the fuel supplier or OEM for LNG safety requirements. Contact with LNG may cause personal injury (freezing).
  • Vent systems on the equipment should be ducted to a safe area whenever equipment is in an enclosed area.

Refer to section for leak checking procedure. ‪
