1533 air filter housing - dump valve (duck bill)

[bruceha2000]

OK, I know this is a little thing but I managed to lose mine. I THINK I put it on top of the radiator housing when cleaning the air filter and forgot to put it back on. Nowhere to be seen after using a compressor to blow junk off the radiator and around the battery. Looks to be a really common housing, anyone know the size of this thing or a part number? I found "uxcell 5pcs Replacement Parts 075 Rubber Air Filter Cleaner Duckbill Valve Black" on Amazon but I have no idea if it would fit (and hopefully I wouldn't need 5 of them".
