8in 0-90 OHM Sender

The 8in 0-90 OHM Sender is an essential fuel or temperature gauge sender for custom automotive builds and restoration projects. As a mechanic working on everything from classic restorations to modern performance modifications, you'll recognize this as a critical link between your tank or engine and your dash gauges. Whether you're fabricating a custom fuel system, upgrading instrument cluster readings, or restoring a vintage gauge cluster, this sender delivers the variable resistance signal your gauge needs to display accurate readings across its full range.

Built to industry-standard specifications, the 8-inch 0-90 OHM Sender operates across the full 0–90 ohm resistance spectrum, allowing your analog gauge to sweep from empty to full (or cold to hot, depending on application). The sender's 8-inch length makes it suited for mid-depth tanks or mounting positions where space is constrained, while the ohm rating ensures compatibility with standard automotive gauge movements found in most aftermarket and OEM clusters. Its compact profile—measuring 3.5 x 3.5 inches at the mounting face and weighing just 0.8 lbs—means it integrates cleanly into tight engine bays and custom fabrication work without adding bulk or requiring extensive bracket modifications.

This sender is ideal for hot-rodders, restoration specialists, and fabricators working with custom fuel or cooling systems where OEM senders are unavailable or incompatible. It pairs seamlessly with vintage Stewart-Warner, Sun, or modern programmable gauges that read 0–90 ohm output. Installation requires a simple threaded or flanged mount into your tank or engine block, depending on your application, and direct wiring to your gauge's sender terminal. For anyone building a reliable custom instrument package or retrofitting gauges into a non-original platform, this robust sender ensures you'll always have accurate, real-time feedback on critical engine parameters.
