Fuel Line Question

[mercurymang]

What is the standard fuel line size (ID) on a mid 70's outboard (have a 75 650 as well as an 850). I suspect it's 5/16 but cant confirm that anywhere. Last time I tried to get some locally I had trouble finding it. Otherwise I would just get a couple of feed and see if it fit. Anyway, if anyone knows for sure I would appreciate it.

I use 5/16" line on my motors that are under 75 HP, and go to 3/8" line for anything over that. I buy most of the fuel hose online by the reel of 25' as I usually use it up in a year or so. Shorter lengths can be bought. Just search the web on your computer for it. JMO

Agree with old on 5/16 for that hp. I am currently running automotive fuel line after my Quicksilver OEM gray fuel line failed me. No problems.
