just curious as any water crossings I have been through so far was under the gas cap. in looking at it, (I have the canam locking one) do you think that tiny seal down there on cap is going to keep water out of tank under water for 5 minutes at a time? anyone ever have issue with water penetration thru cap? just wondering before my next ride as I will be in a river crossing 18-22 inch deep. looks like it would noy be to reliable, when submerged, but I could be very wrong. any one have experience in that area or done it ok.
