filter fit fine for replacing damaged one. price is a little ridiculous and does not come with the breather elbows or formed hoses. removing old elbows from old filter was difficult. they are plastic and damage easy if pliers are used. cut a X in rubber of filter first. use 5/16 fuel hose to replace the surely rotted breather tubes.
