There's no single fuel pressure specification for all 1993 Jeep Wranglers. The fuel pressure depends entirely on the engine installed. A 4.0L inline-6 will have a different fuel pressure than a 2.5L 4-cylinder. Furthermore, the pressure can vary slightly depending on engine temperature and other operating conditions.
To find the correct fuel pressure for your specific 1993 Jeep Wrangler, you must consult your owner's manual or a reliable repair manual specific to your Jeep's engine. These manuals will provide the correct specifications.
