Df115 fuel line

[djbinding]

What is the size fuel line for 08 df115? From water separator to priming bulb and then to fuel filter?

I ran 3/8 from separator to fuel tank and 5/16 under cowling.

my best answer would be.. what size are the fittings you are connecting fuel line to?
you are not going to tie a 3/8 fuel line to a 1/4 fitting or the other way around
