Gas cap leaking, vent hole, spitting gas out gas cap, briggs, tecumseh, power mate generator, lawn mower, small engine.

SOLVED:  Vibration in gas tank causing seepage out of gas cap vent.  RESONANT Frequency (vibration).   Gas cap leaking, vent hole, spitting gas out gas cap, briggs, tecumseh, power mate generator, lawn mower, small engine.    Need BAFFLES inside tanke, but what, how, to make them, **   

(Quick Note:  the spiral hose baffle idea did work just enough to tame the fierce and violent agitation of the gasoline in the tank which was spitting it out the vent hole in the gas cap (even though the generator appeared to have only normal vibration it must have hit coincidentally the resonant frequency which makes it most violent creating the gasoline "water" spouts that cause the seepage out the cap vent ;   I use two 2 foot lengths of the blue hard plastic electrical conduit with ribs (one was not enough),  I may add a third, also its important to get the tubing/conduit directly below the gas cap to break up the fiercely vibrating gasoline ; its probably worth mentioning that this "Power Mate Coleman" generator gas tank is not from briggs and stratton but the motor is Briggs & Stratton 3.5 HP.   So it goes... the using of a non B&S gas tank accidentaly created a resonant freq situation which resulted in gas venting out gas cap.  

My problem is with coleman powermate gas tank agitation at jus the right frequency to cause water spouts (gas spouts really) inside the tank which in turn causes gas to seep out of vent hole... really I ran the generator without the gas cap on and it was like a blizzard of spitting gas coming up quite violently.   SO... after replacing gas line, filter, installing 1 way check valve in gas line, gas cap, etc.  i realized its just hitting the "Resonant Frequency " for that tank size/shape and probably only BAFFLES will solve this BAFFLING probem (lol).   I'm trying to think what to use for baffles that are uninstallable in case they don't work well,,  maybe 1or 2" sections of 3/4" PVC?  2 liter bottle caps.  they must not block the fuel outlet in bottom of tank.    OR perhaps a plastic tubing perhaps 2 feet long coiled in a spiral inside the tank would deflect the resonant waves into a non-resonant patter preventing the gas spouts from popping up with the vibration of the motor.  (all this seems unlikely but believe me its happening). 

on and on... life goes on... never thought this would happen .   * Resonant frequency is the freq that oscillates just right to cause a big wave build up for example that would break a wine glass when the opera singer hits just the right note (frequency) that vibrates the glass to build up a wave that breaks the glass (has to be crystal glass of course).   In physics, resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at specific frequencies. Frequencies at which the response amplitude is a relative maximum are known as the system's resonant frequencies or resonance frequencies.   IE Like when peacniks marching across a bridge hit the resonant vibration frequency and the bridge collapses. 

**  IMPORTANT:  for float plane type aircraft that take off and land on water, its very important to have baffles inside the air pylons that support the airplane (make it float) because if there are no bafffles inside the floats then when the plane takes off and levels off all the water inside the leaky floats rushes to the front and puts the plane in a FATAL nosedive... this has happened alot of times with tragic results. 

  Today is a good day to turn your life over to peace btw, you will have to eventually choose either the laws of man or the laws of God, why not avoid the last minute rush?
