Fuel Sending Units for EFI, LS Swaps & In-Tank Pump Installs

Upgrade your fuel system with precision using high-quality fuel sending units from Hot Rod AN LLC. Whether you're converting to EFI, performing an LS swap, or updating a classic vehicle with a modern in-tank pump, these fuel sending units make it easy to get the job done right.

Our sending units are engineered for seamless integration with popular fuel tanks and fuel cells, providing accurate fuel level readings and compatibility with in-tank fuel pumps. Designed for EFI conversions, these units are the perfect solution for ensuring proper fuel delivery and maintaining system reliability under all conditions.

Why You Need the Right Fuel Sending Unit

✅ Allows for direct installation of EFI-compatible in-tank fuel pumps

✅ Provides accurate fuel level readings to your factory or aftermarket gauge

✅ Includes proper fittings and connections for a clean install

✅ Helps reduce fuel slosh when paired with baffle-equipped tanks

Important Fitment Note: While some sending units will physically fit older or non-EFI tanks, it’s strongly recommended to use a baffled EFI-style tank to prevent fuel starvation and slosh—especially under acceleration or cornering.
