Fuel line sizes for 1960 evinrude fastwin 18 #15032

[boyd66k20]

Maybe someone could direct me to the fuel line sizes under the shroud of model 15032 Evinrude 1960 fastwin 18hp. Hard to tell as they are original. Looks like 2 sizes. Can I get them at the local auto parts store too? Thanks in advance

I use 1/4" and 3/16" from Advance Auto Parts. OK, I know those are not the "official" sizes, but they fit well. Works for me.

(Take a fitting or the fuel pump with you to the store to make sure.)
