Warning: Refer to the precautions
given i n Section 1 before starting
Check
1 The fuel tap is located on the underside of
:9e fuel tank on the left-hand side. Remove
any body panels as required for access (see
Shapter 7). The tap is automatic, operated by
a vacuum drawn through the vacuum hose
+om the inlet manifold when the engine is
turned over (see illustration).
2 The tap should not be removed from the
:ank unnecessarily to avoid the possibility of
damaging the tap body O-ring or the filter. If
r'le fuel tap-to-tank joint is leaking, first ensure
:hat the tap retaining clip is tight (see
illustration 2.1). If leakage persists, drain the
rank, remove the tap and fit a new O-ring (see
Step 8).
3 If fuel flow problems are experienced, first
check that the breather hole in the tank cap is
clear and that the tap vacuum hose is in good
condition and its connections are air tight,
2.9 Clean the filter and check it for holes
then remove the tap and check the tap filter
(see Step 9).
4 If the filter is clean and in good condition,
check the operation of the tap diaphragm.
Disconnect the fuel and vacuum hoses from
the carburettor and place the free end of the
fuel hose in a suitable container below the
level of fuel in the tank. When vacuum is drawn
in the vacuum hose, the diaphragm should
open and fuel should flow from the tank.
5 If there is no fuel flow the tap is blocked
internally; the tap is a sealed unit and must be
replaced with a new one.
6 If fuel flows from the tap with no vacuum in
the vacuum hose, the diaphragm is faulty and
the tap must be replaced with a new one.
Removal
7 Disconnect the fuel and vacuum hoses
from the carburettor and place the free end of
the fuel hose in a suitable container below the
level of fuel in the tank. Create a vacuum in
the vacuum hose and drain the tank. If the tap
is blocked, remove the tank to drain the fuel
(see Section 3).
8 Loosen the clip securing the tap and withdraw
the tap assembly (see illustration). Check the
condition of the O-ring and replace it with a new
one if it is damaged. Note: The O-ring is not
3.4 Tank is held in place by the storage
compartment fixings (arrowed)
listed as a separate item; consult a Peugeot
dealer or automotive parts supplier who may be
able to supply a suitable alternative.
9 Allow the filter gauze to dry, then clean it
with a sofi brush or compressed air to remove
all traces of dirt and sediment. Check the
gauze for holes (see illustration). If any are
found, a new tap should be fitted as the filter
is not available as a separate item.
Installation
10 If removed, install the fuel tank. Ensure
the O-ring is correctly positioned on the tap,
then push the tap into the tank with the fuel
union facing towards the front of the machine
and tighten the clip securely.

Removal
1 Remove the storage compartment (see
Chapter 7).
2 Disconnect the battery negative (-ve) lead
and disconnect the fuel gauge sender wiring
connector (see Chapter 9).
3 Disconnect the fuel and vacuum hoses
from the unions on the fuel tap (see
illustration 2.1).
4 Lift the tank off the frame noting how it is
retained by the storage compartment fixings
(see illustration).
A
Warning: If the fuel tank i s
removed from the scooter, it
should n o t be placed in an area
where sparks o r open flames could ignite
the fumes coming o u t o f the tank. B e
especially careful inside garages where a
natural gas-type appliance i s located,
because the pilot light could cause an
explosion.
