It's a 12 volt DC.to 5 volt converter. 12 volts in 5 volts out simplicity in itself......plus it's relatively inexpensive.....?????.....however it offers no protection like the RTEngineering's unit...the choice is yours.....

I bought something similar. Amazon.com: SIGANDG 12V to 5V DC Converter Car Power Voltage, Step Down to DC 5V 3A 15W Waterproof Buck Converter, Supply Step-Down Module Compatible with Vehicle Car Truck Volt : Electronics. Im going to try it on my 67 Charger. I'm just wondering if I really need to take out the old one in the fuel gauge, can I leave it in and just not have any power to it.

I'm going to try a buck converter to step down 12v to 5v. Seems like it would work and a lot cheaper. Something like this on on fleabay.

These put out a solid 5 volts. Is that ok to use?

Running these types of voltage reducers will work, gauges will react slower on start-up and may require re-calibration. And, as Bob pointed out, it would not contain the gauge protection of the RTE units. Some of these linear regulators will go full 12 volts should it fail or lose its ground.
