Agusta seem to have this better thought out. The fuel filters are heated by the engine oil, so that fuel with FSII isn’t required.
Interesting. Only familiar with the PWC powered 109 and a bit on the139. The 109 definitely doesn't have a heated filter and pretty sure the PT6 powered 139 doesn't either as the FMM is basically the same.
They both do have fuel/oil heat exchangers on the accessory gearbox but the engine fuel filter is part of the FMM.
