retainer, make sure the connection is secure and
the tabs (A) are firmly locked into place; check

make sure you remove the ring pull (C) upwards
after you confirm the connection is secure.

NOTE: Before you remove the ring pull, make sure
the fuel line connection is secure. If the connection
is not secure, the ring pull could break when you try
to remove it.

turn the ignition switch to ON (II) (but do not
operate the starter motor). The fuel pump will run
for about 2 seconds, and fuel pressure will rise.
Repeat this two or three times, then check that
there is no leakage in the fuel supply system.
