My 390 is on teh hard, and since it has been warm and the high angle the bow is in, some gas was leaking out of the vent on starboard side. I loosened the fill cap and all stopped leaking, however, yard asked me to drain 10 or so gallons out. Sounds easy! HOWEVER, when i tried to put a 5/8” ninny l hose down the fill pipe it went in about 3’ or so and stopped. I moved it around, twisted it, etc, but it made a sound like it had bottomed out in teh tank, however, the end was not wet. So i figured there may be a screeb(?) at the tank inlet? I went to HD and got a 3/8” poly ice make line, as it is stiffer, and again, teh same thing happened. I turned and twisted, but after 10 minutes I gave up.

Does anyone know if there is a screen/grate at the filler neck on top of the tank? All I can think of ..

Thanks !
