A note about fuel tank mounting.
Beckson Marine does NOT recommend your using deck plates for access directly into a fuel tank.
Through the deck above the tank? OK. But into the tank itself? No.
The diesel fuel will "eat up" the molded o-ring over time and allow fuel to leak - a totally unacceptable situation. You are better off using an aluminum or stainless steel plate and a diesel-compatible gasket material, attaching this plate onto the tank with through-bolt fasteners.
