This invention relates to fuel tanks of out- Fi 'ure 4 is a sectional "iew of the 10 ular board motors. Out board motor engines are pet-cock. i; I extremely hard to start and at times it is im-' Referring to these drawings, 10 designates possible to start the engine and sometimes. it a fuel tank-Which in ordinary circumstances 3 1 I takes from fifty to seventy-five efforts before will be 11 ,43 inches long by 4% inches. wide 5 the engine will start. This is not onlyjexand 3% inches deep. The floor 11 of this tank tremely irritating to put it mildy, but often extends downward toward one corner of the leads to accidents in vwhich the person starttank as shown and from this low corner of the ing the motor is injured. Ihave found, after tank extends a pipe 12 connecting with a' 1 many years of experience with out-board mohollow pet-cock body 13 having a tap 14 at 60 I tors, that the trouble is caused by the sweatitslower end.- Above this pet-cock body 13, v ing of the gas tank, moisture gathering on a pipe-15 extends to the carburetor provided the inside of the gas tank and gradually with a tap or valve 16. I do not wish to be trickling down into the'gasoline and settling limited tov the particular form of pet-cock 15 to the bottom of the tank. This is particularnor to the particular form of valves except 65 ly due to the fact that the fuel slopsaround as stated in the claims. This gas tank may. in the interior of the tank and gathers up this be supported by two arms extending out from water. Furthermore sediment gathers in the the muffler and fastened to the same. I do j H V bottom of" the tank and when an attempt is not wish to be limited to this, however. i J

As a consequence, of course, the charge body. Before starting the engine,- the tap 14 will not explode, the engine misses fire and 1s opened and one or two'tablespoonfuls oft attempt after attempt must be made until the mixture of water and foreign matter are this water has been discharged.
