TEST INSTRUCTIONS
POPPET & FLOAT MOVEMENT
FOR TESTABLE MODELS ONLY
TOOLS NEEDED FOR TESTING:
1. 1/4” square drive extension or 3/8” square drive ex-
tension with 3/8” to 1/4” socket adapter.
2. Torque wrench / 1/4” or 3/8” square drive ratchet
wrench.
3. Pipe dope.
4. Flashlight (optional).
TEST STEP 1:
Remove spill container cover and ll cap from ll adapt-
er and look down into the tube and make sure no debris
or foreign objects are present. If debris or foreign ob-
jects are present take appropriate steps before proceed-
ing. Look down into the tube and ensure poppet is
completely protected by the deection shield. See Test
Figure 1. If poppet is exposed and tank is not full the
overll valve should be replaced. A ashlight may help
when inspecting the tube.
TEST STEP 2:
Unthread the socket adaptor assembly from the inlet
tube using a 1/4” square drive extension and wrench.
The extension will attach to the socket adaptor. Secure
all tools to ensure they don’t fall into the tank or valve.
With the extension still attached pull on the socket
adaptor and cable assembly and ensure oat and pop-
pet move / function properly. It should only require 3”
to 4” of movement and less than 5 lbs of force in order
to actuate the oat and poppet. When looking down
into the upper tube ensure poppet is visible and moves
into the ow path (see Test Figure 1 & 2) when socket
adaptor is pulled and resets properly when socket adap-
tor is released. If poppet does not actuate freely take
appropriate steps to correct.
TEST STEP 3:
Apply pipe dope to the socket adaptor threads. Pipe
dope should be a non-hardening gasoline resistant pipe
thread seal compound. Make sure poppet and oat
have reset properly and are not visible then install sock-
et adaptor and torque to 3.5 ft-lbs (42 in-lbs) minimum
to 5.0 ft-lbs (60 in-lbs) maximum. After installing socket
adaptor, to ensure vapor tightness, OPW recommends
conducting pressure testing per CARB TP201.1D. Some
areas may require pressure testing of overll valve per
CARB TP201.1D to ensure valve is vapor tight. If the
drop tube fails pressure testing it may be necessary to
check the seal at the poppet adaptor threads. Reinstall
ll cap and spill container cover after testing.
