Radium Fuel Level Senders and Accessories | Universal (20-0847-203 / 20-0146 / 18-0020)

A fuel gauge that still works after a hanger swap is worth the small part that makes it happen.

Radium Engineering fuel level senders and accessories for in-tank installations: a shrouded 0-90 ohm sender, a block-off for unused sender openings, and the 5-bolt gasket.

Choose Your Part

• Fuel level sender, 0-90 ohm, 8.0in shrouded (20-0847-203)
• Fuel level sender block off (20-0146)
• Gasket, 5-bolt fuel level sender (18-0020)

What You'll Feel

• A working fuel gauge after a tank or hanger modification
• A clean seal over an opening you no longer use
• A shrouded float arm that resists slosh interference

Features

• 0-90 ohm sender, 8.0in shrouded
• Block-off plate for unused sender openings
• Replacement 5-bolt gasket

The Details

Ohm range has to match what your gauge or ECU expects. This sender is 0-90 ohm, which is a common range but not universal, so confirm before ordering. Worth knowing for dual-cell and saddle tank builds: wiring two 0-90 ohm senders in series creates a 0-180 ohm range, or they can feed independent ECU inputs, which is how a passive-side sender can be used to control a lift pump.

The block-off is for openings left behind when a sender is relocated or deleted, and the 18-0020 gasket is a service item worth replacing whenever a 5-bolt sender comes out, since a compressed gasket will not reseal reliably.

Applications

• Universal, in-tank fuel level sending applications
• Radium fuel cells and custom tank installations

Important Notes

• Confirm your gauge or ECU expects a 0-90 ohm range
• Replace the gasket whenever the sender is removed
