Have a quick question about these gauges....
I want to get one of these and add the fuel pressure sensor to the gauge. However, I want to make sure that I purchase all that is needed for the install. On the website, it offers the 4AN fitting and 5V regulated power supply. What I need both of these items to complete my install of the fuel pressure sensor??

I will be installing this on a supercharged Silverado SS (2003)

Thanks in advance!

 

Yes you will unless you tap the sensor into a pre-existing 5V power source. You'll need to refer to a maintenance manual to find one. Your better off just going with the regulator.
