I need to replace waste & water caps but they are not standard sizes like the fuel fills... can anyone point be to the correct ones? Thanks, Brian
Brian, I think the Cap threads are 1-1/4" x 11-1/2 NPSM-Straight that are available from multiple vendors (Seadog, Seachoice, Atwood, Perko). I like the color coded ones, with the pull-up handle as an added safety factor and no tool required. https://marine-products.com/collections/fuel-fills-caps
