Fuel Lines Sizes

[Caddis295]

I am replacing all my fuel lines but I need to know what sizes I need for my 89 Johnson 40hp. Any idea?

I purchased a new tank to motor fuel line/bulb assembly. Just need the internal stuff.

Thanks,

Re: Fuel Lines Sizes

OMC used to say: "Anything over 85 HP requires 3/8" ID". There was a tag on the hose.

Many of the smaller engines were 5/16".

I run nothing but 3/8", on everything, just to keep it simple.

The fuel hoses at the power head are 5/16,5/32, the small one for the primer outlets are 1/16 i.d.
