FUEL FILTER AND LINES
If the fuel filter/water separator has
not been recently replaced, it is highly
recommended that this be done at
this time. Check vehicle owner’s
manual and factory service manual
for replacement intervals and service
procedure.
FUEL TRANSFER (LIFT)
PUMP
The fuel transfer pump supplies fuel
from the fuel tank through the fuel
filter/water separator to the high
pressure injection pump. It is a 12-volt
vane-type self-priming pump mounted
to the left side of the engine behind
the fuel filter/water separator. Check
fuel lines to and from pump for leaks,
kinks, or other restrictions. A pump
with external housing leaks must
be replaced. Clean the area around
the pump and filter/separator before
performing the following test.
FUEL TRANSFER PUMP
TEST
If a factory service manual is available,
refer to the Fuel Transfer Pump Test
in the Fuel System portion of the
manual. Otherwise perform the test as
indicated.
For ‘01-02 trucks, proceed to Step 3.
1.
Remove the two hex plugs from the
top of the fuel filter/water separator
housing and replace them with two
inline check valve fittings. Use the

number AVU1-2 Access Valve, Male
Connector or equivalent. See Figure 1.

Install a fuel pressure test gauge
with appropriate hose fitting to the

of the fuel filter housing (This is the
