Fuel System - General Information - Fuel System Pre
ssure Check
Gen
eral Procedures
WARNING: Working on the fuel system re sults in fuel and fuel vapor being present in the atmosphere. Fuel vapor is
extremely flammable, hence great care must be taken whilst working on the fuel system. Adhere strictly to the following
precautions:
D
o not smoke in the work area
Di

splay
NO SMOKING signs around the work area
D
isconnect the battery before
working on the fuel system
Av
oid sparks
Make sure sui

table fire ex
tinguishers are at hand
Make sure absor
bent material is at
hand to soak up any spillage
Make sure the work area is
well ventilated
M

ake sure that the gauge is correctly conn
ected, and that all connections are secure BEFORE starting the engine
DO N
OT
disconnect the gauge from the schrader valve while the engine is running
Make su
re the schrader valve reseals once the gauge is disconnected
• NOTE: Depending on the design of the ga uge set, there may be a drain valve and tube. Make sure this valve is closed, and
the drain tube placed in a suitable container BEFORE connecting the gauge to the schrader valve.


1. Make sure the vehi
cle is in
Park for vehicles with automatic
transmission, Neutral for vehicles with manual transmission.
2. Apply the parking brake.
3. Place suitable absorbent material around the schrader valve to
absorb any spillage when connecting the gauge set.
4. Remove the protective cap from the schrader valve.
5. Connect the gauge, using adaptors if required.
6. Remove the absorbent material and dispose of safely.
7. Disconnect and plug the vacuum hose from the pressure
regulator.
8. Start the engine and record the fuel pressure reading.
As a gui
de, the fuel pressu
re should be approximately 3.0
bar (44.1 psi) with the regulator disconnected.
9. With the engine still running, reconnect the vacuum hose to
the pressure regulator an d record the reading.
Th
e pressure should dr
op to approximately 2.6 bar (38
psi) when the vacuum hose is reconnected.
10. Switch off the engine.
11. Place more absorbent material around the schrader valve.
12. Where fitted, open the drain valve and allow the fuel from the
gauge and line to flow into the container to depressurize the
system.
13. Disconnect and remove the gauge set and any adaptors.
14. Clean up any fuel which may have been spilt and remove the
absorbent material. Dispose of safely.
15. Refit and secure the protective cap to the schrader valve.
16. Reconnect the fuel pressure regulator vacuum hose.
17. Start the engine and make sure there are no leaks.

sides and the engine compartment rear cover.
8. Cut, remove and discard the ra tchet strap which retains the
throttle cable to the abutment bracket.
9. Ensure there is no tension on the throttle cable by releasing
the throttle cable adjustment nut from the abutment bracket.
10. Record the voltages for both sensors, PPS11 and PPS2.
11. Partially insert the throttle cable adjustment nut into the
abutment bracket.
12. Recheck the voltages for both sensors, PPS11 and PPS2.
13. Where the voltages at step 12 are higher than the voltages
taken at step 10, contin ue to step 15 below.
14. Where the voltages at step 12 are the same as the voltages
taken at step 10, contin ue to step 16 below.
15. Rotate the adjustment nut clockwise (as viewed from the
front of the vehicle) until the same voltages are indicated as in
step 10. Continue to turn thro ugh a part revolution until the
sides of the nut are vertical. Tu rn through a further 90 degrees,
then fully insert the nut into the abutment bracket.
16. Rotate the adjustment nut anti-clockwise (as viewed from the
front of the vehicle) until the indicated voltage starts to
increase. Then rotate the nut clockwise through a part
revolution until the sides are ve rtical. Turn through a further 90
degrees, then fully insert the nut into the abutment bracket.
17. Fit a new ratchet strap to secure the throttle cable adjusting
nut to the abutment bracket.
18. Operate the throttle pedal through 20 full cycles to settle the
cable. Check the voltages now shown, remain the same as in
steps 15 and 16.
