How many pumps does it support?

Hoses included for two pumps, with dual 6AN outlets and a single 6AN return.

Is it E85 compatible?

Yes — Type II hard anodized, ethanol compliant, with PTFE fuel lines included.

What's the difference between "Hanger Only" and "Hanger & Relay Kit"?

"Hanger Only" includes the hanger along with all hoses, connectors, filters, and extensions needed for installation. "Hanger & Relay Kit" adds the relay harness on top of that.

Does it retain the factory fuel level sensor?

Yes — the factory fuel level sensor isn't part of the fuel pump hanger assembly, so it's unaffected by installation. It stays in its original location elsewhere in the tank.
