11in 0-90 OHM Sender

The 11-inch 0-90 OHM sender from JAZ is a precision fuel level measurement instrument designed for automotive enthusiasts and fabricators building custom fuel systems. Whether you're restoring a classic vehicle, converting a fuel tank in a race build, or installing an aftermarket fuel cell, this electromagnetic sender converts tank capacity into a readable gauge signal on your dashboard. As someone who's swapped fuel systems and calibrated gauges countless times, I can tell you that a quality sender is non-negotiable—it's the bridge between your tank and your instrument cluster, and accuracy directly impacts how you manage fuel consumption during long drives or competition events.

This JAZ sender operates across a full 0–90 ohm resistance range, meaning it outputs a complete sweep of resistance values as the float moves from empty to full. The 11-inch length makes it compatible with deeper tanks and custom fabrications where standard senders won't reach the bottom. The sender's design relies on a reliable potentiometric float arm mechanism—as fuel level rises or falls, the float moves linearly, varying the electrical resistance proportionally. This linear response is critical for accurate gauge readouts; any nonlinearity in the sender will create dead zones or erratic needle behavior on your gauge. The compact 3.5 × 3.4-inch flange and lightweight construction at 0.95 lbs make installation straightforward even in tight tank configurations or retrofit situations where space is limited.

This sender is ideal for custom build applications, race vehicle fuel system upgrades, and fuel tank replacements where OEM senders don't fit or won't meet your specification. Hot rodders, fabricators, and serious DIY builders who demand precise fuel monitoring for tuning and endurance runs rely on JAZ senders for their proven accuracy and robust construction. Installation requires matching the sender's 0–90 ohm output range to a compatible fuel gauge calibrated for the same resistance curve—mismatches will cause needle deflection issues. Verify tank depth and flange mounting style before purchase to ensure proper fit; the 11-inch dimension refers to the sender's immersion length, so your tank cavity must accommodate this fully submerged.
