Then how do you know you can turn it OFF if you need to?
Because I ripped out all of the fuel lines, replaced the worn gascolator, renewed the selector, and at the 50 hr, and each annual we check it. I also check it once a month. The comment was I leave it on after each flight. Given I am the only one that flies my plane, I am quite happy with it.
Mainly due to this incident
