Thanks Dusty, I had already founf this discussion right after I posted, Got the new ones on order for @$7
Does not look like a big job, just loosen up the 2 bolts and the top screw and just push it up and pull out ther old one and place in a new one.
it's important to see the new o-ring stays in place while re-installing it. I use a little grease to hold it in place. I also pull each intake off completely to do so.
