Thanks for the insight! I bought a Racor yesterday with the steel bowl and will be draining the tanks this weekend. The vents look like they will be a beast to change around, but thats the only place the water could be coming in.

RAP, could you post a picture of where your vents are, mine are BELOW the rubrail, did you move your to the top of the deck, near the fill fitting??
