Remove and discard the plastic temporary plug from the fuel delivery pipe and re-connect the
pipe to the fuel pump outlet tube. Make sure the connector is all the way onto the outlet tube
then lock the slider. Tug on the fuel delivery pipe to be sure it is fully locked in place.
IMPORTANT REMINDERS: Discard the removed temporary fuel line plug as it is a one-time use
item. Reusing the plug may damage the connector’s internal o-ring and cause a fuel leak.
•
Ensure both the pipe and tube are clean and dry
•
If the slider does not move easily, confirm the pipe is engaged on the tube
•
ALWAYS confirm the pipe is fully engaged after connecting and check for any leaks
13. Reconnect the harness connector to the fuel pump.
14. Reconnect the ground cable and harness connector to the battery sensor. While supporting the
sensor with one hand, torque the 12mm ground cable nut to 7.5 Nm (5.5 ft. lbs.).
15. Turn on the ignition switch to run the fuel pump. The engine does not need to be started. Check
closely for any leaks around ALL fuel delivery tube connections removed as part of this repair
(including those under the hood if fuel was drained) and around the ring nut.
16. Reinstall the inspection cover.
17. Reinstall the r/rear second row seat and trim in reverse order of removal. Torque the retaining
bolts to 53 Nm (39 ft. lbs.) Make sure the seat belt buckles are properly positioned.

APPENDIX A
Replacement Fuel Pump Component Installation Tips
These tips have been assembled to help Technicians successfully complete these repairs quickly
and accurately by identifying and clarifying specific repair areas which could lead to concerns after
reassembly. These conditions may include fuel supply concerns resulting from o-rings that are:
•
Damaged or torn
•
Out of position, pinched or stretched
•
Improperly installed in relation to the bushing (o-ring and bushing positions reversed).
CRITICAL STEP: After removing the
original fuel pump component from
the filter housing, ALWAYS confirm
the original o-ring either came out
with the pump or, it is removed from
its bore BEFORE attempting to
install the new fuel pump as shown
here.
Both the illustration and picture below show the proper configuration of the fuel pump, bushing and
o-ring prior to reassembly. The new o-ring is positioned for proper sealing on top of the bushing.
A - NEW O-Ring Supplied in the Parts Kit
B - Bushing (Reused from Original Pump)
The images below are snapshots from a video which shows how the o-ring can become compromised
when repeated attempts are made to press / force the new fuel pump back into the filter housing. A
small “window” was cut into the filter housing used here to visually demonstrate how when repeated
attempts are made to get the new pump to engage the retaining claws of the original filter housing, the
o-ring can become dislodged from the fuel pump outlet tube and damaged. The new o-ring shown
below has been colored YELLOW to make it easier to see.
Continued...
Bulletin Number: WRD-20R Revised Date:08/27/21
Page 44 of 51
Three prime reasons for Technicians to have difficulties with getting the new pump to fully seat /
latch back into the filter housing properly are:
•
The original fuel pump o-ring is still in place in the filter housing bore
•
The new o-ring was not properly lubricated with gasoline prior to attempting the reassembly
•
Repeated attempts to get the pump fully seated have caused the o-ring to come off the outlet tube
of the fuel pump as shown below.
CRITICAL TIP: Align and press the new fuel pump FIRMLY, SQUARELY and STRAIGHT into
the filter housing in ONE smooth, continuous motion.
VERY IMPORTANT: When pressing the fuel pump into the filter housing, if it does not seat
properly with all the retaining clips “clicking” into position MUST be removed from the filter
housing, the bushing and o-ring “reset” and the o-ring re-lubricated before trying again. Do this with
each attempt to assemble until successful. If the o-ring becomes pinched, stretched or otherwise
damaged, it MUST be replaced.
VERY IMPORTANT REMINDER: When installing the new fuel pump into the filter hopusing,
it is CRITICAL to press the new fuel pump FIRMLY SQUARELY and STRAIGHT into the filter
housing in ONE smooth, continuous motion. Misalignment will prevent the o-ring from seating
squarely in the bore and when the hand pressure is released to try again, the o-ring can easily become
dislodged from the fuel pump outlet tube resulting in the mis-alignment shown above and in the
illustrations below.

The RED circles represent a cross-section of the o-ring.
OK
The new fuel pump is being pressed firmly and squarely into the filter housing bore and successfully
“clicks” into place.
NG
Here, the new fuel pump is being pressed into the filter housing bore at an angle which will likely
result in the outlet tube butting against the shoulder of the bore the o-ring seals against followed by
repeat attempts which often end up with the o-ring becoming dislodged.

APPENDIX C
Fuel Tank Leak Test
•
The Fuel Tank Leak Test MUST be performed on ALL models after fuel pump
replacement has been performed. This will ensure proper sealing of the fuel tank
chamber.
(STEP :1) Using the Redline Detection Smoke Pro (RDL-950051), apply 10kpa (1.45 PSI) at the vent tube. These pressures
for this test are higher than those specified when confirming proper
sealing of the fuel pump. Check to ensure the pressure is retained
for 10 seconds. Is the pressure retained?
YES – The inspection is complete. Reassemble the removed parts in the reverse order.
NO – The pressure is not retained. Possible improper installation of the gasket, ring nut or
fuel pump upper plate is suspected. Check the installation condition and replace any damaged
part(s) with new. Re-install correctly and perform this inspection again.

Subaru Safety Recall WRD-20
NHTSA Recall ID 20V-218
June 2020
Dear Subaru
Owner:
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.
SUBARU OF AMERICA, INC. has decided that a defect, which relates to motor vehicle safety, exists in certain 2019
model year Ascent, 2019 model year Impreza, 2019 model year Legacy and 2019 model year Outback vehicles.
You received this notice because our records indicate that you currently own one of these vehicles.
REASON FOR THIS SAFETY RECALL
Your vehicle may be equipped with a low-pressure fuel pump assembled with an impeller that may become deformed.
Over time, the impeller may become deformed enough to interfere with the body of the fuel pump, potentially causing
the low-pressure fuel pump to become inoperative.
SAFETY RISK
If the low-pressure fuel pump becomes inoperative, the check engine warning light or malfunction indicator light may
illuminate, and/or the engine may run rough. An inoperative fuel pump may result in the engine stalling without the
ability to restart the vehicle, increasing the risk of a crash.
WHAT SUBARU WILL DO
Subaru will replace the fuel pump at no cost to you.
What You Should Do
You should contact any authorized Subaru retailer (dealer) for an appointment to have this safety recall repair
performed, at no cost to you.
HOW LONG WILL THE REPAIR TAKE?
The time required to replace the fuel pump for Impreza, Legacy and Outback vehicles is approximately 1 hour and 10
minutes. The time required to replace the fuel pump for Ascent vehicles is approximately 1 hour and 40 minutes. Your
retailer can provide you with a better estimate of the overall time for this service visit, as it may be necessary to make
your vehicle available for a longer period of time.
For your convenience, your retailer may provide you with a loaner or rental vehicle, at no cost to you, until the repair is
complete.
CALIFORNIA REGISTERED OWNERS
The California Air Resources Board requires that emission related campaigns be completed prior to California’s
vehicle registration renewal process; without this repair, you will not be able to register your vehicle during your next
annual registration. Upon completion of this campaign, your California dealer will complete and provide you a “Proof
of Correction Certificate.” If required, present the certificate to the California Department of Motor Vehicles (the
“DMV”) when renewing your California registration as proof of campaign completion. If the DMV does not request the
certificate, we recommend that you keep it for your records.
In addition, the State of California requires that every vehicle must pass an emission test (SMOG Check) every two
years and before it is sold. Without the repair we are providing at no charge, your vehicle may not pass this test.
