SPECIAL TOOL(S)
1. Measure the length of the damaged area of the mini-tube vacuum hose.
2. Cut a piece of standard 3 mm (0.125 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.
