1234700393. I thought I had ordered it already and confused it with the purge valve, which is three-pronged instead of two. An ebay seller had old OEM stock, so I just ordered. I just wonder, depending on how old it is, is it a rubber diaphragm that can go bad with age?

If it doesn't work, has anyone tried the 1244760432 as an alternative? It looks like, from photos, that it could work.

I haven't tried it, but came close to buying that part recently with advice from the excellent MBL.
If it fits then big relief.

I just got an oem three pronged one that goes to the canister.
The two one goes under the car near the fuel tank, correct ? Keep us posted if that part works...
It is a good idea to change it as it could affect the fuel tank pressure...
