What's the ideal fuel line for under the cowl? Brand/type?

I'm getting an older outboard into shape. Mercury 75HP made in '86. The brittle fuel lines I tore out yesterday were marked SAE 30R7.

A website that sells fuel lines has this in the description: "30R7 is not Coast Guard approved for marine applications".

Pep Boys carries a hose from CADNA in the size I need (50086) that says low pressure/high temp but nothing about marine applications.

So what's best to run from the fitting to the fuel pump, then from the pump to the carbs?
 
"marine applications" is somewhat ambiguous.....30R7 rated hose doesn't comply with the "A1-15" requirements....that said, that hose is for inboard use (or with a permanently installed fuel tank)...

If you run with ethanol blended fuels, get a hose that will handle it. I'd suggest a brand name hose vs a no-name type.
