This CAN-SB fuel gauge and cap drops straight into a tank with 160 mm depth and gives you a simple dial right on top. The float runs up and down about 160 mm inside the tank and shows level on an easy face. The cap footprint suits common portable marine tanks where depth is close to 160 mm. You get a straight mechanical reading without wiring or power to worry about at the ramp.

The cap is moulded from tough marine plastic with metal guide rods around 4–5 mm thick holding the float steady. The dial window is roughly 40–50 mm wide so you can check the coloured segments in a glance on choppy water. Italian-made hardware from CAN-SB means tidy machining and smooth float travel over the full 160 mm. For Aussie boaties this is a smart buy to keep an eye on fuel in small runabouts and tinnies.

Q: Does this fuel gauge cap need any electrical wiring?

No, this fuel gauge cap works purely as a mechanical gauge. A float moves up and down a rod inside the tank and turns the pointer on the dial. There are no wires or senders to install. That keeps the setup simple on small boats and makes replacement straightforward.

Q: What tank depth is this CAN-SB fuel gauge cap suited to?

This gauge cap is matched to tanks with a depth of about 160 mm. The float travel and rod length are set around this measurement. On significantly deeper or shallower tanks the dial reading will not line up with the actual volume. Check your tank depth before ordering to get the right match.

Q: Can I use this gauge cap on any portable plastic fuel tank?

You can only use this gauge cap on tanks with a matching thread pattern and a depth close to 160 mm. Many CAN-SB and similar style tanks share this style of cap. If your existing cap looks different or your tank is much deeper than 160 mm, the gauge may not fit or read correctly.

Q: Is this gauge suitable for checking fuel level while under way?

Yes, the dial can be read while the boat is operating, but short-term slosh will move the float and pointer. The best practice is to glance at the gauge once the boat settles on a straight run. Treat the reading as an approximate level, and still plan fuel use with sensible safety margins.
