Fuel Line

[davidk]

What’s a good replacement for the fuel line that goes from the fuel fitting to the carb on a 1956 Johnson Javelin 30hp?  Would that be 5/16″?

Split your double line and use one side… or 3/16 will work with a quality clamp.

I found that 3/16 works well, 3/32 (I think) seems to work well too.

Dave I would say that the 30hp needs the 5/16″ line.   It might be tough to get the 3/16 on those bigger fittings.  40hp motors use 3/8″ line.   JMHO

Here’s the carburetor off my ’56 Johnson 30hp which is the standard model (not a Javelin) and this carb uses 3/16″ fuel line.   I would assume your carb is the same as this one as the only difference between the standard and Javelin models was the cowling cosmetics.

The other difference is that my carb is not as clean and shiny as yours. : )

Well, if you’re replacing the fuel line you can always shiny up the carb too!! LOL
