I have a 2000 S80 T6 2.8L that's throwing a P0442 "small evap system leak" code.

Can anyone tell me the correct part number for the J-Hose that connects to the Evap cannister?

From reading the posts here, that hose sounds like the most likely failure (crack or split in the hose).

But I see at least 6 different part numbers for the hose, and don't know which is correct.

Thanks for your help.

 

Answered my own question, and for anyone else who may need it...

The J-hose is part number 1270255. (about $20+)

And if you're throwing a P0455, and it's not from your gas cap, check the EVAP purge valve located on the radiator shroud. It is part number 9470775. (Close to $40.) Don't forget to change the two small (~ 3 inches long) EVAP hoses connected to the purge valve. They are 5/16" or 8mm fuel/evap line.
