What is the normal fuel pressure for a 1990 Chevy pickup?

The normal fuel pressure for a 1990 Chevy pickup varies depending on the engine. There's no single answer. You need to know the specific engine (e.g., 4.3L V6, 5.0L V8, 5.7L V8, 6.2L V8, diesel) to determine the correct fuel pressure.

To find the correct fuel pressure specification, you should:

1. Consult your owner's manual: This is the best source of information.

2. Look up your engine in a repair manual: A Haynes, Chilton, or factory service manual will have this information.

3. Use a reliable online automotive resource: Websites like GM's own resources or reputable repair sites may list the specifications. Be sure to specify the exact engine.

Without knowing the engine size and type, any fuel pressure I provide would be inaccurate and potentially harmful.
