DODGE RAM SRT-10 2006 Service Repair Manual LINES - FUEL
DESCRIPTION
Low-Pressure Lines Are:
the fuel supply line from fuel tank to fuel filter housing.

the fuel drain (manifold) line at rear of cylinder

LINES - FUEL
DESCRIPTION
Low-Pressure Lines Are:
the fuel supply line from fuel tank to fuel filter housing.
the fuel return line back to fuel tank.
the fuel drain (manifold) line at rear of cylinder head.
the fuel supply line from fuel filter to fuel injection pump.
the fuel injection pump return line.
High-Pressure Lines Are:
the fuel line from fuel injection pump to fuel rail.
the 6 fuel lines from fuel rail up to injector connector tubes
WARNING: High-pressure fuel lines deliver diesel fuel under extreme pressure from the injection pump to
the fuel injectors. This may be as high as 160,000 kpa (23,206 psi). Use extreme caution when inspecting for
high-pressure fuel leaks. Inspect for high-pressure fuel leaks with a sheet of cardboard. High fuel injection
pressure can cause personal injury if contact is made with the skin.
OPERATION
High-Pressure Lines
CAUTION: The high-pressure fuel lines must be held securely in the brace. The lines cannot contact each
other or other components. Do not attempt to weld high-pressure fuel linesor to repair lines that are dam-
aged. If lines are ever kinked or bent, they must be replaced. Use only the recommended lines when
replacement of high-pressure fuel line is necessary.
High-pressure fuel lines deliver fuel (under pressure) of up to approximately 160,000 kPa (23,206 PSI) from the
injection pump to the fuel injectors. The lines expand and contract from the high-pressure fuel pulses generated
during the injection process. All high-pressure fuel lines are of the samelength and inside diameter. Correct high-
pressure fuel line usage and installation is critical to smooth engine operation.
WARNING: Use extreme caution when inspecting for high-pressure fuel leaks. Inspect for high-pressure fuel
leaks with a sheet of cardboard. High fuel injection pressure can cause personal injury if contact is made
with the skin.
DIAGNOSIS AND TESTING
HIGH-PRESSURE FUEL LINE LEAKS
High-pressure fuel line leaks can cause starting problems and poor engineperformance.
WARNING: Due to extreme fuel pressures of up to 160,000 kpa (23,206 psi), use extreme caution when
inspecting for high-pressure fuel leaks. Do not get your hand or a finger near a suspected leak. Inspect for
high-pressure fuel leaks with a sheet of cardboard. High fuel injection pressure can cause personal injury if
contact is made with the skin.
Start the engine. Move the cardboard over the suspected high-pressure fuel line leak, and check for fuel spray onto
the cardboard. If line is leaking, retorque line while engine is shutdown.Replace damaged, restricted or leaking
high-pressure fuel lines with the correct replacement line.
CAUTION: The high-pressure fuel lines must be clamped securely in place inthe brace. The lines cannot
contact each other or other components. Do not attempt to weld high-pressure fuel lines or to repair lines
that are damaged. Only use the recommended lines when replacement of high-pressure fuel line is neces-
sary.
