  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. WARNING: Read the warning information on the product label to prevent possible personal injury.
  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.
