  "definition": "1. Meaning given in 40 CFR 1054.801.\n\n2. Hose, tubing, and primer bulbs containing or exposed to liquid fuel, including hose or tubing that delivers fuel to or from the engine, as follows:(1) This includes flexible molded sections for transporting liquid fuel to or from the engine, but does not include inflexible components for connecting hose or tubing.(2) This includes hose or tubing for the vent line or filler neck if fuel systems are designed such that any portion of the vent-line or filler-neck material continues to be exposed to liquid fuel after completion of a refueling event in which an operator fills the fuel tank using typical methods. For example, we would not consider a filler neck to be a fuel line if an operator stops refueling after an initial automatic shutoff that signals the fuel tank is full, where any liquid fuel in the filler neck during the refueling procedure drains into the fuel tank.(3) This does not include primer bulbs that contain liquid fuel only for priming the engine before starting.\n\n3. All hoses or tubing designed to contain liquid fuel or fuel vapor. This includes all hoses or tubing for the filler neck, for connections between dual fuel tanks, and for connecting a carbon canister to the fuel tank. This does not include hoses or tubing for routing crankcase vapors to the engine's intake or any other hoses or tubing that are open to the atmosphere.\n\n4. Hose or tubing designed to contain liquid fuel (including molded hose or tubing). This does not include any of the following:(1) Fuel tank vent lines.(2) Segments of hose or tubing whose external surface is normally exposed to liquid fuel inside the fuel tank.(3) Hose or tubing designed to return unused fuel from the carburetor to the fuel tank for handheld engines.(4) Primer bulbs that contain liquid fuel only for priming the engine before starting.\n\n5. Hoses or tubing designed to contain liquid fuel. The exhaust standard-setting part may further specify which types of hoses and tubing are subject to the standards of this part.",
