autometer fuel pres. gauge

I just put an Autometer Feul Pressure gauge and a reg. on my car and I can tell you that the fitting that goes into the back of the gauge is not one I could find at the local parts store. So what I did was find the nearest hydralic (sp?) place and went to the them with it and they got me what I needed and it was 1/8th the price that Autometer wanted. If I was you I would like I said try to find a shop that deals in hydralics and they will be able to help you out.
Good luck!

I got a new fuel pressure reg. and the gauge at the same time, so I re-placed the existing fuel pressure reg. with the new one and it has a port in it for the line to the gauge. There is a way to get a special fitting that replaces the threaded fitting that is on the fuel line up at the front of the car on the passenger side I think, but I am not sure how it works, so I just spent the money for an adjustable Feul pressure regulator and ran the line from it to the gauge, this way I am able to adjust the pressure to what I want.
I hope this helps you in some way.
Let me know if I can be of anymore help.
