## Questions & Answers

**Q: Im doing a flex fuel conversion on a 2000 trans am. Will this sensor work with a 2002 chevy Tahoe operating system for flex fuel?**
A: Yes

**Q: 2020 Silverado 5.3 would it fit?**
A: It would if you have the harness for it if not you are better off getting a E85 kit for your truck instead.

**Q: Does this sensor also measure fuel temperature?**
A: Yes - this sensor also measures temperature.  The ACDelco (or Continental) flex fuel sensor outputs a PWM signal that is from 50hz to 150hz for % ethanol content and encodes the fuel temperature in the PWM duty cycle.  You need some specific circuitry or an intelligent ECU to extract both % ethanol and fuel temp from the signal pin that is in the 3-pin connector.

**Q: What size quick connector do i need ?**
A: 3/8”
