Where can I purchase the clear 1/4 inch fuel pump vent line that goes to the flame arrestor? The line I have is not long enough. I would like to get 4 ft. of it. I purchased the Tygon (spelling) stuff, but it kinked easily on the bends.

Its basically the same quarter inch fuel line used on snowmobiles and other similar engines. I would think a snomobile/atv dealer or supply store would carry it. Also local hardware store as small engine fuel line

It is not a vent line.
It is there in case the fuel diaphram ruptures. It runs to the carb so that the fuel does not dump into the bilge.

A hardware store would have 1/4" vinyl hose. Lowes, Home Depot or your local store.

Yep I know. That's why I want to make sure I get fuel line. Got it from my local motorcycle shop.
