I'm getting a little tired of not being able to top off the FW tank, without running the risk of overflowing, and than siphoning the tank back down to the 1/2 tank level.
Consequently, I'm thinking seriously about adding a riser to the tank vent...sort of a vacuum breaker, but, and I know this is stupid, haven't yet found the tank much less how to access it.
Has anyone else addressed this problem?? I know I can fill it until the CMP shows 100%, but I'm unclear as to how much capacity is left unused at the 100% level. Also, if it's near full....say at 100%, is there a possibility that driving will cause the water to slosh around, fill the vent tube, and start the siphon while on the road?
