I HAVE THE CORRECT PART NUMBER......I LEFT A NUMBER OUT
I just contacted Julio and he informed me that he could not help me. Said they don't sell to individuals.
He sent me to their website to find a local dealer.

Make sure to select Marine air on the check box on top
PART NUMBER 331314 cost .55 each.
The guy told me there were additional numbers so I added the 290
NOTE The guy that actually made the order said it needed to be looked up at the old part number, without the 290, what a mess for such a simple part
