Another Fuel Line Question

I plan to replace the under the cowl fuel lines on my 89 evinrude.
Looking at the factory spec sheet, I need 5/16 from the fitting to the fuel pump and 3/8 from the pump to the carbs.
All the factory hose that I can find are in 25 foot lengths, and I only need less than 2 feet of each.
My local marine shop only has A1 in stock, which I believe will be too large of an OD to fit in the space allocated.
Will regular fuel line suffice under the cowl? If not, does anyone have a source for a by the foot supplier of the proper hose?
Thanks

Got mine off ebay, many there will sell it to you by the foot, or as they call it, "By the unit".

Most auto parts stores sell it by the foot.

Bought mine at Advance Auto by the foot. Had both sizes.

So apparently just regular fuel line is ok for under cowel.
Thanks for the replies.
