97 Chevy cavalier fuel line size?

The fuel line size on a 1997 Chevy Cavalier isn't a single size. There are multiple lines with varying diameters. You'll have a larger diameter line from the tank to the engine, and smaller lines for return and potentially vapor lines. There's no single definitive answer without knowing *which* fuel line you're referring to.

To find the correct size, you'll need to:

1. Visually inspect the fuel line: The easiest way is to measure the inside diameter (ID) of the line itself at the point where you need the replacement. Use a fuel line diameter measuring tool or carefully insert a calibrated probe.

2. Consult a repair manual: A repair manual specific to your 1997 Chevy Cavalier will list the specifications for the fuel lines.

3. Check with a parts store: Auto parts stores (like AutoZone, Advance Auto Parts, etc.) can usually look up the correct fuel line size based on your vehicle's year, make, and model. Providing the VIN would be even more helpful.

Without more information, I can't give you a precise fuel line diameter. Attempting to guess could lead to incorrect part selection and potential safety hazards.
