I have them too... and am very satisfied!!!. I have not really measured how much more fuel I can add, but it appears to be at least 3/4 of an inch.
I understand your concern on the overflow questions, I had them too.
To satisfy my own doubts... I tried to make them overflow by putting every drop of fuel I could in our tanks, knowing that if they did - we had a place to capture and deal with the additional fuel.
We arrived in Fruita CO and filled up the Seneca until the fuel was half-way up the extensions and capped them off. (we could not take another drop of fuel) We proceeded 5 miles to the concert venue where we stayed five days without running our on-board generator except for the first 3 hours after we arrived and were setting up our camp. (we brought an auxillary gen set for the entire group of RV's we partied with)
We went the entire week without any fuel expansion/escape from our tanks - period. We did come prepared with two oil-drain pans that we put under our tanks, as I actually anticipated that we would have some overflow. Since we were running an auxiliary diesel generator - that was where the overflow fuel was planned to go - but never had to.
