SPECIAL TOOL(S)

1. Measure the length of the damaged area of the mini-tube vacuum hose.
2. Cut a piece of standard 1/8 inch inner diameter vacuum hose approximately 25 mm (1 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 hose ends in commercially available paint thinner containing Methyl Ethyl Ketone (MEK). This solvent will seal the mini-tube in the vacuum hose.
