It appears to me that pouring the seals would be wrong because of the overfill.
Not pouring the seals would be improperly installing the seals unless using them as an expensive conduit connector is okay.
If the area is misclassified for the fuel, then the seals should be removed.
I have a feeling that the engineering plan is uniform for multiple fuels, one of which may have heavier vapors, and the fill requirement was overlooked.
