shown discontinuous in fig4 a thru 4 d at some point in time after fig4 a as shown in fig4 b inside film 32 and outside film 33 have sufficient size and momentum to overcome any discontinuity between surface 18 and surfaces 22 or 23 the fuel that formerly collected at the discontinuity now clings to endface surface 18 due to adhesion between the fuel and the aluminum spout material the fuel adhered to surface 18 forms a potential fuel drop 34 when fuel drop 34 becomes sufficient in size to cause necking drop 34 soon falls in the direction of gravity fig4 c shows drop 34 just prior to it breaking free of endface surface 18 the process of inside film 32 and or outside film 33 creating drop 34 continues until an equilibrium is reached shown in fig4 d equilibrium can occur from multiple events one potential mode of equilibrium occurs when films 32 and 33 are too thin to overcome the discontinuities of surface 18 the result is a bulge of fluid between surfaces 22 and or 23 and endface 18 another equilibrium event occurs when film 32 and or film 33 evaporates faster than its propensity to flow this is likely to occur in very warm operating conditions lastly equilibrium can occur when drop 34 is insufficient in size to cause necking as previously mentioned improved endface surface 18 u2032 according to the present invention.
