Best Overall: Rupse Fuel Tank

Buy on Amazon

If you often find yourself scrambling for good gauge, rupse fuel tank should be your first option for buying. Although the gas gauge assembly comes with instructions, it still takes some skillful common sense to install. It's a floating arm type. The gauge sensor is configured for a shallow fuel tank, like a 6" deep tank, and the float mechanism does not have enough float leverage to move freely up and down with gas level changes. It is made of stainless steel, and the interior is controlled by high-quality reed switches. The sender adjusts 3 ways for width and depth of the tank.

The top of the tank has a section in the center that is lower than the ends. The tank has to be grounded to make the gauge work and the one wire is the power. The unit comes with a rubber seal, so yes it gets sealed.

• You can bend the float arm to adjust for any angle
• Very nice gage and easy to install
• Pretty universal for most sized gas tanks

This gauge is not waterproof at all. It only can return to Zero while it connects to the fuel sensor before the motorcycle start work. The backlight will begin to flash. This is a great upgrade/replacement digital gauge.
