Measure the length of the damaged area of the mini-tube vacuum hose.
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).
Cut off the mini-tube vacuum hose on each side of the damaged area.
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.
WARNING: READ THE WARNING INFORMATION ON THE PRODUCT LABEL TO PREVENT POSSIBLE PERSONAL INJURY.
Insert the ends of the mini-tube vacuum hose approximately 9 mm (3/8 inch ) into the ends of the standard 1/8 inch repair vacuum hose section.
Shake the repair joint after assembly to make sure the solvent is dispersed and the vacuum line is not plugged.
Test the system for a vacuum leak in the repair area.
