372 vent leak

[Robthetreemanct]

I have a 372 with the old vent just black tube with 2 stone type pieces inserted. I just replaced the parts and it is still leaking any ideas? I'm very frustrated at this point.

Did you use one of these also, part #503600401? Usually stops the problem.

Yes I have the smaller stone in the vent itself and then the larger one. I'm thinking the tube isnt seating in the tank properly I'm going to pull it all apart again today. Maybe a small runner o ring in the tank seat will help

It's strange there is no valve in these vents. The fuel just comes right through the stone

id just use a little seal-all or fuel resistant gasket maker of your choice on the outside of the black plastic tube that goes in.

Correct... But usually they don't leak much if you are running the saw. Usually just a prob if you store them full or idling on side for a while... If you have a wrap handle its not as much of a prob either
