Help Please!! Fuel pressure regulator...fuel spraying out

I have been trying to solve my fuel pressure regulator problems on a 1997 TA. I've already removed the entire fuel rail and came to this conclusion...I have an aeromotive adjustable one and it doesn't have clamps to connect the fuel line to the regulator....Does anyone know where I can get one of these clamps...or modify it....Thanks

The Areomotive regulators have a port for a pressure gauge which requires a plug if it isn't used. My Aeromotive was missing that plug.

Also, Aeromotive makes a regulator for the LTs which should be a bolt-on without any modifications. Here is a photo. Notice the plug in the Red body of the regulator.

You can buy a set of plastic disconnect tools at AZ for a few bucks, has 3 or 4 different sizes.

Supply line is 3/8", the return line is 5/16".

The bracket that holds the two fuel lines is not what "holds it inside". There is a small C-clip that slides over the flange on the fuel pressure regulator and the flange on the fuel line. You can see the edge of it in the photo. There should also be an O-ring on the end of the fuel line.

Thanks, Looks like I'm missing the C-clip...I took off the entire fuel rail and got everything nice in tight except the plug in back of aeromotive is leaking so I need to find a new one....Any idea where to find these c-clips...or should i make my own custom clamp??
