Mine leaked because the gasline was too big for the carb nipple, and a clamp was almost impossible to get in there ---just not enough room I finnaly found a smaller diameter gas line that would fit really tight on the tank but perfect on the carb. It was not see thru which I dont like but it does not leak,which means I can keep it in the basement .

My wife can smell a gas leak 2 blocks away. If momma aint happy nobodys happy
