HIGH FUEL SYSTEM PRESSURE

DIAGNOSIS AND TESTING

FUEL SUPPLY RESTRICTIONS

LOW-PRESSURE LINES

Fuel supply line restrictions or a restricted fuel filter can cause starting problems and prevent engine from
accelerating. The starting problems include; no start, longer cranking times, low power and/or white fog like
exhaust.

Inspect all fuel supply lines for restrictions or blockage, including the fuel filter. Flush or replace as necessary.

HIGH-PRESSURE LINES

Restricted (kinked or bent) high-pressure lines can cause starting problems, poor engine performance, engine
mis-fire and white smoke from exhaust.

TESTING FUEL INJECTORS

WARNING:

High-pressure fuel lines deliver fuel under extreme pressure from the
injection pump to the injectors. This may be as high as 1600bar
(23,200psi). Use extreme caution when inspecting for high-pressure fuel
leaks. Fuel under this amount of pressure can penetrate skin causing
personal injury or death. Inspect high-pressure fuel leaks with a sheet of
cardboard. Wear safety goggles and adequate protective clothing when
servicing fuel system.

CAUTION: High-pressure lines cannot contact each other or other components. Do

not attempt to weld high-pressure fuel lines or to repair lines that are
damaged. High-pressure lines can be reused only after close inspection
for cracks or deformation around the sealing cone. Corroded pipes must
be replaced. Use only recommended lines when replacement of high-
pressure fuel line is necessary.

NOTE:

High-pressure fuel lines must be replaced at each disassembly.
