FAQs

How do I choose the right deck fill for my boat?
When selecting a deck fill, consider the type of tank you are filling (fuel, water, or waste), the size of the fill opening, and the material of the deck fill. It's important to choose a fill that is compatible with your tank's specifications and meets marine safety standards.

Are deck fills universal, or do I need specific ones for my boat?
Deck fills are not universally compatible; they come in various sizes and designs for specific applications. It's essential to select deck fills that match the dimensions and requirements of your boat's tanks to ensure proper fit and function.

How do I install a deck fill?
Installing a deck fill typically involves cutting an appropriate-sized hole in the deck, securing the fill with screws or bolts, and ensuring proper sealing to prevent leaks. It's recommended to follow the manufacturer's instructions carefully or consult a marine professional if you're unsure about the installation process.
