SPECIAL TOOLS
1. Measure the length of the damaged area of the mini-tube vacuum hose.
2. Cut a piece of a standard 1/8 inch inner diameter vacuum hose approximately 25 mm (1 mini-inch longer than the damaged area of the mini-tube
vacuum hose).
3. Cut off the mini-tube vacuum hose on each side of the damaged area.
4. Dip the mini-tube vacuum hose ends in commercially available paint thinner containing Methyl Ethyl Ketone (MEK). This solvent will seal the
mini-tube in the vacuum hose.
WARNING: READ THE WARNING INFORMATION ON THE PRODUCT LABEL.
5. Insert the ends of the mini-tube vacuum hose approximately 9 mm (3/8 inch) into the ends of the standard 1/8 inch service vacuum hose section.
6. Shake the service joint after assembly to ensure the solvent is dispersed and the vacuum line is not plugged.
7. Test the system for a vacuum leak in the repair area.
