1986 Ford Aerostar V6-183 3.0LSECTION Service and Repair
If a nylon tube is broken or kinked, and the damaged area is 1/2-inch or more from a connector; the tube can be repaired by cutting out the damaged section, but not more than 1/2-inch, and then installing a rubber union, Figure 2.
If the remaining hose is too short or the damaged portion is more than 1/2-inch: replace the entire hose and connectors with rubber vacuum hoses and a tee. Use existing service stock of 5/32-inch hose, 7/32-inch hose and tees.
NOTE: Circled numbers, Figure 3, identify same connection points on both original and repaired harnesses.
CAUTION: Care must be exercised to keep all vacuum parts away from hot components such as EGR tubes and exhaust manifolds. In addition, holes may be worn into the nylon hoses if allowed to rub against rough surfaces.
