It is recommended that drip collectors required on all updraft carburetors be drained by __________. (small passenger vessel regulations)

Correct Answer: Option B — a device to automatically return all drip to the engine air intakes

46 CFR 119.458 requires that drip collectors on updraft carburetors be drained by a device that automatically returns the drip to the engine air intakes. This prevents the accumulation of hazardous fuel vapors in the bilge, significantly reducing the risk of fire or explosion within the engine compartment.
