Previously posted a question on replacing all fuel line on a Briggs Intek V-Twin 25HP on our JD 155C tractor. Decided NOT to go with Tygon.  Anyway, the tractor's up in Michigan and will be doing this in April.
 
Hence the the "dumb" question:  If I'm right, correct size used in this application is 1/4" ID x 1/2" OD?   The only problem I could run into is a sharp bend where the line comes out of the pickup tube at the tank.
 
(Would like to have the line in hand before I head up North since there's no place to buy cut lgths bulk up there.  10ft max is more than enough)
 
Thanks!

If 5/16" hose fits, I'd use that.
 
A for the turn:

Not a bad idea Scott.  Will be adding an inline fuel shutoff as well.  Just need to determine the best location when the time comes.
