This spring I replaced water and diesel fuel deck fills. I bought stainless deck fills from Marine Part Depot, which is relatively inexpensive foreign made stuff but was robust and fit the old holes nearly perfectly. They unscrew using one of those bronze spanner wrenches you can buy from Groco. (Im sure there are other wrenches that fit.) After removing the old chrome-plated deck fills, I gouged out some balsa coring on the inside of the open holes, wetted the core with West System, and filled in the gouged out areas with a West System/colloidal silica mixture. I then used a round sanding drum to smooth the inside surface and fit the replacement deck fills, and I also isolated the deck screws with epoxy. I then installed the replacement deck fills with a good sealant. Inside, I used Groco 1 ½ stainless hose barbs, which is admittedly overkill. I suspect most people use a plastic hose barb for this purpose.
It sounds like a lot of work, but it wasnt too bad.

Somehow all the standards have changed since the original were installed. I am in a similar boat; most of my fill caps are worn, not working or temporary. I need to replace all three (water, waste and fuel). Is there a recommended, good fill that is reasonably easy to install and will not require half of the boat to be redone?

The diesel cap has worn to the point where the winch head [of the handle] no longer fits well. Has anyone found a suitable replacement? I see several possibilities at Defender, but Im concerned the threading wont match exactly. Or, has anyone made a plug or insert for the deck fill, maybe a large hex nut welded to a threaded rod?
