What size fuel line is stock

[polar]

Basically trying to figure out what size the stock fuel line is and what size flare is on the end

3/8 feed and 5/16 return. The flares on the ends should be just a normal flare.

3/8" pressure and 5/16" return, but on the 98 I believe you have the O-ring style fittings. You can buy adapter lines at most parts stores.
