Hunter 49 Waste Tank Deck Fitting Size

If you're asking what size a replacement cap or pumpout connector needs to be...1.25".
The specified size for "deckfill" fittings (water, waste and fuel are all identical except for "water," "waste" etc etched into the flange)--can be confusing. USCG regs require 1.5"...but that only applies to the tailpiece (the part the hose tank discharge hose goes onto 'cuz that's standard hose size for all fill and waste tank discharge hoses). The flange on deck fitting with a 1.5" threaded opening has too large a diameter to fit on the side deck of most US production boats, so they all have 1.25" threaded openings, and so do all European boats produced for sale in the US.
