For Ford and some Chrysler vehicles: Install the Ford port adapter on the throttle
body or fuel rail test port, FINGER TIGHT ONLY, then connect the gauge hose to
the adapter.
For GM and some Chrysler vehicles: Connect the gauge hose directly to the test
port, FINGER TIGHT ONLY.
e. Place bleed-off hose into an approved drain container. MAKE SURE the hose remains
in the container until testing is complete.
f. MAKE SURE all of the vehicle's accessories (air conditioner, fan, radio, defroster, lights,
etc.) are turned off.
g. Turn ignition on and listen for fuel pump activation (most systems will activate the fuel
pump circuit for approximately two seconds when the ignition is initially turned on to
prime the fuel system). Check the test setup and MAKE SURE no fuel leaks are present.
If fuel leaks ARE present, turn off ignition IMMEDIATELY and repair any leaks. BE
SURE TO CLEAN UP FUEL SPILLS IMMEDIATELY.
If your fuel system does not operate as described in step g, or if fuel system is not
operating properly, refer to the manufacturer's service manual for repair
procedures or activation instructions.
h. When the fuel pump has been activated in step g, the fuel system is pressurized. Verify
the tester gauge indicates a system pressure which corresponds with the specifications
provided in your vehicle's service manual. If the fuel pressure is within vehicle
manufacturer's specifications, proceed to step j. If pressure is not within manufacturer's
specifications, proceed to step i.
i. Turn ignition off and follow the test and repair procedures in your vehicle's service
manual to correct the problem. After all necessary repairs have been completed, return
to step g.
j. Start and idle engine. RECHECK THE TEST SETUP FOR FUEL LEAKS.
k. Read fuel pressure from the tester gauge. If the fuel pressure is within vehicle
manufacturer's specifications, proceed to step m. If pressure is not within manufacturer's
specifications, proceed to step l.
l. Turn ignition off and follow the test and repair procedures in your vehicle's service
manual to correct the problem. After all necessary repairs have been completed, return
to step j.
m. Turn ignition off.
n. MAKE SURE that the bleed-off hose is still
routed to the drain container. Press and hold
the relief valve to bleed off system pressure.
Hold the relief valve until the tester gauge
indicates 0 (see Figure 5).
o. Shake the bleed-off hose to ensure all residual
fuel has been expelled.
p. Wrap a shop rag around test port area to avoid
fuel spray and
CAREFULLY disconnect the gauge hose from
the port adapter.
If installed, remove the Ford adapter from
the vehicle's test port.
q. Remove the bleed-off hose from the drain
container and hold both gauge hoses over the
container to let any remaining fuel drain. Store
the tester in a well-ventilated area to dry
completely.
r. Recheck all fuel system connections, then start
the engine. Check for any leaks and repair as necessary.
The engine may crank for several seconds before restarting.
