Chapter 5: Fuel Tanks and Fittings
CFR Yacht Test for Fuel-Fill Spill Compliance
Take care that the natural flow of any spilled or dripping fuel cannot run back into the boat through any path. Think
through the locations carefully. If you are inspecting or surveying a boat and it appears that fuel spills potentially could
enter the boat, be sure to note this as a problem that needs immediate correction.
The required test under the CFR for fuel-fill spill compliance for gasoline boats is as follows (using water):- Ensure the boat is in its normal static floating position.
- Plug the fuel-tank fill line at a distance at least 6 inches (152 mm) below the tank fill opening.
- Insert a^13 / 16 -inch (20 mm) OD hose into the fill fitting.
- Discharge through the hose at the rate of 5 gpm (53.3 oz. in 5 sec.) or 19 L/min (0.147 L in 5 sec.).
- Fill until the pipe overflows. Time the overflowing water for 5 seconds, and turn off the flow.
- Inspect to determine if any of the overflowing water has made its way into the boat. No water is permitted at
all. Any water entering the boat from this test indicates noncompliance and must be corrected. Overflow
entering a self-bailing cockpit is considered entering the boat and does not comply.
NOTE: Though passing the preceding test is requiredfor gasoline boats, it is strongly recommended for diesel
vessels as well.
