QuestionSince chevy didn't put a test port on my 1993 1500 4.3V6 chevy P/U How do I go about testing my Fuel pressure?
AnswerAutozone will probably lend you a tool for it.
There is a fitting that goes in the line where the filter is, with a test port on it.
There are other adapters that allow "T"'ing into the connection at the throttle body also.
The pressure should be 13 PSI.
