Weepage tolerance is defined as:

Weepage tolerance is defined as:

• A. Not acceptable in any condition
• B. Acceptable at ejector pump around shifting lever shafts and duplex filters
• C. Acceptable only during testing
• D. Acceptable near the fuel intake

Answer: (B)

Weepage tolerance is the amount of minor leakage that engineers allow in certain components because a tiny seep can be expected in real operation and won’t compromise safety or function. Some seals and interfaces can’t be perfectly leak-free while the system is moving, vibrating, or heating and cooling, so designers specify where a controlled, small amount of seepage is acceptable. The ejector pump area around shifting lever shafts and the duplex filters are such locations. These parts are designed with seals and drainage paths that handle a small, steady weep without affecting performance or creating dangerous conditions. Allowing this limited seepage prevents unnecessary maintenance alarms and avoids misinterpreting normal, expected leakage as a fault. If the leakage were observed in places outside these designated areas, or if it exceeded the specified tolerance, it would indicate a fault requiring attention. In short, weepage tolerance is about permitting small, contained leaks in specific, non-critical areas where the design accounts for them, and the ejector pump around shifting lever shafts and duplex filters are classic examples of where this is acceptable.
