MCI tank panel rub rail removal

[Dave5Cs]

I have a small fuel leak behind the front tire area under the tank area fuel door. There is a small 3/8"s? rubber hose that comes out a hole and then back up into a second hole. It is dripping fuel and is wet. Only way I can get to it is to take off the fuel door whole panel but can not get behind the panel , so how do I get the rub rail off at the bottom. The rest is just rivets I can drill out?
Bus is a MCI 5C
TIA Dave Walker
