37. Tighten Screws (1) alternatively from side to side across cover until all are solidly fastened. Torque to 28-32 in-lbs. (3.2-3.6 Nm)
38. Pressurize the “Fuel In” opening with approximately 100 psi of air pressure. Draw a soap bubble across the Lockoff outlet and vacuum port (labeled “VAC”) to verify that no air is flowing through either opening. If air escapes, the rebuild has failed and the Lockoff must be replaced. Apply a small amount of vacuum to the port labeled “VAC” to verify the air flows freely through the outlet. Use soap and/ora commercial leak detector solution to inspect the gasket seals around the perimeter of the Lockoff for leaks. If leaks are found, the Lockoff must be replaced. If no leaks are found, the Lockoff can be reinstalled and returned to service
