Maretron SAE 5-Bolt Non-Displacement Focus Tube

The Maretron Non-Displacement Hull Focus Tube uses an SAE 5-bolt mounting pattern, giving a sensor mounting point on a non-displacement hull tank where the sensor has to focus its reading through a specific tube geometry to work correctly. Getting that mounting hardware right matters more than it might seem, since a mismatched focus tube can throw off tank level readings even when the sensor itself is working fine.

It's part of Maretron's tank sensor mounting hardware line, built to pair with a compatible tank level sensor rather than functioning on its own as a standalone part.

The SAE 5-bolt pattern matches a common aftermarket fuel sender flange standard, making it a straightforward fit for many existing tank installations that already use that same bolt pattern. Shop more marine networking.
