RACE ON!!!
Same on my '95. There are no AN fittings on a C4 fuel system from the factory. W/o checking for sure, I'm pretty sure it takes a #8 AN hose to get a 3/8" ID.
6AN is equal to the 3/8 size and 5AN is equal to the 5/16 size fuel line. You can go to Aeroquips website to see more information. Look under their "performance" line.

In 88 and up,GM switched to 3/8-3/8 for the lines,over the 3/8-5/16 set up seen in 84-87.
Are you checking the lines at the tank or at the fuel rail hook up on your car?
