Got it. Yup - same boat here so same configuration. The left circle is the T and the right one, I assume (haven't seen it personally, yet) is a 90*. I'll take a closer look - but it might mean another access plate either in the middle of the two drains (might be too tight for that, though) or possibly from the fuel tank compartment. Although, I'd leave cutting a hole in the main stringer as a last resort. Maybe a plate in the floor, instead.
