0 to 100... where are you planning to mount the sender? The fuel rail extender method didn't work for me... It was too tight of an area for the sender.
The easiest way is to install this test tool inline where the engine fuel line connects to the chassis fuel line. Remove the nipple that comes on the tool and install the fuel press sender. (The sender will need to be grounded)
The tool is made by KD. Look here: http://www.toolsource.com/fuel-injection-pressure-tester-adapter-pressure-p-58494.html
