While replacing fuel pump I noticed another fuel line that goes from the canister behind the passenger wheel and is just venting to open air near the wheel. From looking at the service manual it appears this is supposed to go to the carburetor, but it is not clear to me where on the carb it goes.

This line is not long enough to reach the carb now (I susupect it was cut by a P.O.

Also this is just a rubber fuel hose. After all the discussion in the "no start: topic, I have some reluctance about running fuel taks up over the engine. But on the other hand I guess this is not going to be under pressure, and shold just be vapor?

What is the suggested routing from the canister to the carburetor? How long of a line do I need to buy?

Greetings:

Hopefully, these pictures may offer some small assistance:

My hose had three secure points - A ty-rap to the frame member between the canister and the frame clamp, the frame clamp, and a ty-wrap by where it ran up next to the fuel pump hose and into the base of the carburetor - Sorry I do not have a close up picture of the hose into the base of the carburetor - Not sure if that is the best way to secure the hose line, but it is the way mine was.

I may still have the hose around and can measure it if you would like.

problem is
this is the "vapor lock" hose
