Hi everyone i was wondering what size of fuel line on the primer bulb would you guys use for a 1974 evinrude 15 hp model 15404s. 3/8 or 5/16. :?: . Thanks
My 20 hp Merc has 5/16" I use the stuff from the Mercury store that is suppose to stand up to ethanol, it's $2.79 a ft. Another place in town wanted $5.49 a ft for it.
