I purchased a set of digital gauges for my truck. I need a fitting for the fuel pressure sensor that can hook up to the factory fuel line on my 00 Silverado. I want to hook it up to where you would check the fuel pressure on the factory fuel logs. The fitting on the sensor is a male fitting that has a thread size of 1/8" - 27NPT. I dont know what the size is on the factory fuel line itself. Any help would be great.
