It is recommended that drip collectors required on all updraft carburetors be drained by?

• A. A device to automatically return all drip to the engine air intakes
• B. Manual drain valve
• C. Gravity drain to bilge
• D. Closed drain to fuel line

Answer: (A)

Drip collectors on updraft carburetors are there to catch excess fuel that drips from the carburetor and return it so it can be burned in the engine rather than spilled. Using an automatic device that returns all drip directly to the engine air intakes keeps fuel out of the bilge, reduces fire risk, and ensures the dripped fuel is burned in the cylinders for proper operation. Relying on manual drains requires operator action and can lead to spills; draining to the bilge creates a hazard, and sending drip back into a fuel line is not appropriate for this purpose.
