High Pressure Fuel Pipe, Left Pump to Rail, LML | 2011-2016

This is the genuine GM high-pressure fuel pipe (GM 12670474) that runs from the injection pump outlet to the left-hand fuel rail on the 2011-2016 LML 6.6L Duramax. It carries fuel at injection pressure, so it's a steel line built to GM's original dimensions.

Key Features

• GM part number 12670474
• Position: injection pump outlet to left-hand fuel rail
• High-pressure steel line, silver finish
• Length: 21.68 in
• Outside diameter: 0.25 in; inside diameter: 0.118 in

Benefits

High-pressure lines are formed to exact bends and seat dimensions, so a GM line seals correctly at both the pump and the rail. Replace if worn or damaged. A leaking or damaged line can let fuel escape and cause a loss of rail pressure. Many shops replace both pump-to-rail lines when the injection pump is replaced.
