International 9300/9370 Fuel Tank Senders

Frequently Asked Questions About International 9300/9370 Fuel Tank Senders

What does a fuel tank sender do on my International 9300/9370?

The fuel tank sender is the component inside your fuel tank that measures fuel level and sends that signal to your dash gauge. If your fuel gauge is reading inaccurately, stuck on empty or full, or fluctuating erratically, a worn or failing sender is often the cause.

How do I know if I need a replacement sender versus a new gauge or wiring repair?

Common signs of a bad sender include a gauge that never moves, reads consistently wrong, or jumps around while driving. Before replacing the sender, it is a good idea to check your wiring connections and fuses for corrosion or damage, since electrical issues can mimic sender failure. If the wiring and gauge test out fine, the sender itself is likely the culprit.

Will a sender for the International 9300/9370 fit both tank sizes and configurations?

Fuel tank senders can vary based on tank depth, mounting pattern, and resistance range, so it is important to match the sender to your specific tank configuration rather than assuming a universal fit. Check the listed specifications on each product page and compare them to your existing sender or your truck's build sheet before ordering.

What is involved in replacing a fuel tank sender?

Replacement typically involves draining or lowering the fuel level in the tank, disconnecting the wiring harness, removing the mounting bolts or locking ring that secures the sender, and carefully withdrawing the sender without bending the float arm. Installation is the reverse process, making sure the gasket seats properly to prevent leaks and the wiring connections are secure.

How long should a replacement fuel tank sender last?

Service life depends on usage, fuel quality, and operating conditions, so we cannot give a specific mileage or time guarantee. In general, senders can wear out due to float arm fatigue, resistor wear, or corrosion over years of use, so if you have already replaced one and are having similar issues again, checking for underlying causes like tank contamination is worthwhile.
