what is the diff between marine fuel lines and automotive fuel lines they said the ones i have are not coast guard approved

The CG approved fuel lines resist permeation, fire, heat, cold, ozone and premature aging by all marine fuels including alcohol blends.
You can be sited if you were to be inspected and if your lines do not conform.

Ayuh,.... If the lines don't have the Coast Guard approval printed on 'em,...
Change 'em...

I agree with Bill.
If your fuel lines do not have the correct info printed on them, they may be old fuel lines, in which case changing them is inexpensive, and you gain the benefit.

The marine A1 hose wall thickness is much thicker than the SAE hose of the same ID. As you likely already know, rubber doesn't melt, it burns. Thicker wall thickness gives more more time to put out the fire or get off the boat. Kind of like a "30 minute" fire door. Fire will eventually get thru, but the materials work as barriers to slow it down.

Marine A1 fuel hose is one of the few bargains in the marine world. Its only about 50 cents more per foot than the auto stuff & lasts a long time. Is copper $$ with flair fittings still legal ? I remember when the only place you could use hose was a short piece at the engine for vibration elimination. Those were the days.

Metal fuel lines are still acceptable. Copper lines typically use the (45 deg) flared connections with inverted flare being standard for steel. The "newer" 37 degree AN style flared fittings are vastly superior to the 45 deg types.
