Parts Desk Insights
Best Use Case: Best for replacing or upgrading a below-deck permanent fuel tank where you want a purpose-built poly tank with molded-in fill/withdraw/vent locations to simplify system layout.
Common Issues: Common install issues include mis-matching the deck/hold-down layout to the tank’s stated tank-only dimensions, and assuming the tank dimensions include the fill/connector hardware. Always confirm the mating surfaces, required cutouts, and that the system fittings you plan to use match the tank’s intended configuration.
