VACUUM HOSE CHECK

1.

Using the piping diagram as a guide, check to be sure
that the vacuum hoses are correctly connected.

2.

Check the connection condition of the vacuum hoses,
(removed, loose, etc.) and check to be sure that there
are no bends or damage.

VACUUM HOSE INSTALLATION

1.

When connecting the vacuum hoses, they should be
securely inserted onto the nipples.

2.

Connect the hoses correctly, using the vacuum hose piping
diagram as a guide.
