How do I connect an electric fuel pressure gauge?

[at t 2d]

I am getting ready to purchase an Autometer electric fuel pressure gauge. I have searched the forum and I have not found any installation info. Will I need to purchase something to connect it to the shrader valve on the fuel rail?

You'll need a tool to get the stem/shader out of the fuel rail (I have a small skinny pair of needle nose I use very carefully) and you'll just need a -4AN fitting to whatever your new fuel pressure gauge needs. Let the car sit overnight and the pressure should be out of the line. I still take a few rags and jam them all around and under the fitting to make sure fuel does not spill or get all over anything.

I have a tool to remove the shrader valve, any idea where I would be able to find the 4AN fitting? Is it common?

Should be able to pick a fitting up at a speed shop or maybe even a parts house. Russell makes them as well
