DESCRIPTION

LOW-PRESSURE FUEL LINES

All fuel lines up to the fuel injection pump are considered low-pressure. This includes the fuel lines from the fuel tank to the high pressure fuel injection pump. The fuel return lines and the fuel drain lines are also considered low-pressure lines. High-pressure lines are used between the fuel injection pump and the fuel injectors (Refer to 14 - FUEL SYSTEM - WARNING). Also refer to High-Pressure Fuel Lines Description/Operation (Refer to 14 - FUEL SYSTEM/FUEL DELIVERY/FUEL LINES - OPERATION).

HIGH PRESSURE FUEL LINES

CAUTION: High pressure lines can not contact each other or other components. Do not attempt to repair or weld high pressure fuel lines that are damaged. If lines are kinked or bent, they MUST be replaced. Use only recommended lines when replacement of high pressure fuel line is necessary.

(Refer to 14 - FUEL SYSTEM - WARNING) . The high-pressure fuel lines are used between the high pressure fuel injection pump and the fuel injector rail, and between the fuel injection rail and fuel injectors. All other fuel lines are considered low-pressure lines.
