What can i do or check to see where water keeps coming into my gas tanks? Im thinking its the gas caps.  Anybody have any issues with this before?
When i first got the boat a couple months ago i trained the gas tanks and found about 2 gallons of water between both tanks.  I changed my water fuel seperator filter, filled it up with gas and it ran great. 
Ive been running the boat pretty much every other weekend with no issues.  I do see that water can puddle up right by the gas caps? 
I ran the boat all weekend and saturday i ran the tanks pretty empty.  The next day i filled both tanks and went across lake, boat was runnin great, then it wouldnt wanna start.  Doing the ecxact same thing as when i bought it with water in the tanks!

Any suggestions on higher gas caps? what else can i check to see where water could be coming back in.  Ive already went through both breathers. 

Thanks,
Sorry for the rambling 

Check the vents also as well as the o ring on the gas caps, I'd also swap out the water fuel separator that may help also!!
