Considering the fumoto. From the pics it seems clear that you installed the ADP-107 adapter. Is this really necessary? From the pics it does not really look like the drain hole is recessed.
It's up to you, personally I didn't want to chance it as the fitting starts to rub on the sump paneling before it's completely tight.
It's one of those "you're probably ok" but the adapter is 4 dollars and does not exactly stick out into anything in the way.
