    Tiger Loop Ultra?
    There can't be anything after the Tiger Loop.

    This is acceptable: Tank > overhead fuel line > oil filter > Tee fitting > tiger loop inlet from branch ^ tiger loop inlet from run.

    This is acceptable: Tank > overhead fuel line > Tee Fitting > tiger loop ultra on branch ^ tiger loop ultra on run.

    Both tiger loops: Outlet > burner supply > burner return > tiger loop return. Just like the picture on the box. No other filters between the tiger loop outlet and the burner inlet is required.
