Frequently Asked Questions

Q: What ohm range does this marine fuel sending unit use?

A: This fuel sending unit uses the American standard 240–33 ohm output range — 240 ohms when the tank is empty and 33 ohms when the tank is full. This makes it compatible with the vast majority of US-spec fuel gauges found on boats, trucks, cars, and RVs.

Q: What vehicles and vessels is this fuel sender compatible with?

A: This stainless steel fuel sending unit is designed for broad compatibility, including marine boats, pontoons, fishing vessels, cars, trucks, and RVs — any application that uses a standard 240–33 ohm fuel gauge system.

Q: Why is stainless steel important for a marine fuel sending unit?

A: Stainless steel is highly resistant to corrosion from fuel, water, and salt air — all common in marine environments. A stainless steel sender unit lasts significantly longer than plastic or standard metal alternatives, making it the preferred choice for boat and marine tank applications.

Q: How many mounting/size options are available?

A: This fuel sending unit is available in 7 variants to accommodate different tank depths and mounting configurations. Select the option that best matches your tank's specifications for a precise, leak-free fit.
