On a 1993 4.0 Six cylinder is there a connection port somewhere in the fuel line system where one can connect a fuel pressure gauge in order to determine whether or not fuel pressure is within spec?

I looked under the hood at the fuel rail and fuel lines but did not see one.

thank you

 

I have a 1995. I did not find a fuel pressure port anywhere on it. I disconnected the inlet line from the rail and then used hoses and clamps to put a fuel pressure gauge in-line with the rail. It held together long enough to get a few pressure readings.
