100TECH Fuel-Flow Instruments Editorial Review
The 100TECH Fuel Sending Unit is designed for marine or vehicle usage. From FAQ, it is confirmed that the right OHMs reading for the gauge is 240-33 and it is compatible with regular truck fuel tanks. The unit is easy to install, with some users finding it challenging to attach the screws that come with it, so using old screws is ideal. The gauge had accuracy issues for some users when the tank was over 3/4 full or when they were moving, but for others, it worked fine. One customer experienced failure after a few months. Overall, it's an affordable and easy-to-install replacement for the vertical float sending units used in many boat tanks.
