All of a sudden gas started leaking from the stem coming off the bottom of the float bowl. I looked at my other rancher and there is some tubing come off that stem to drain back by the rear suspension. This rancher has no tubing and all of the gas drained out that stem onto the garage floor. Why did this happen? There must have been something in the bowl that deteriated? The tubing on this one must have fallen off? Guess I'm doing a rebuild.
