Default gastank leak

Yep, I've been down for a year or so, and on a mission to get the vert back on the road. Anyway, I've noticed before I dismanlted the backend that in the past my tank would leak when filling her up on the drivers side, and when sitting in the garage. Now there is maybe a half gallon in the tank presently now that I have it out. I held the tank vertical with the plastic thingy pointed downward and noticed a hose leak at the clamp. Tightened the clamp and held it up again, and didn't notice a leak. But then I tilted it forward and noticed it start leaking again. making me think that the plastic thingy is bad or the hose is a mismatch diameter for the plastic thingy, hose ID looks bigger that black thingy OD.OMG. I think I'm going to try and find a tighter hose. In the meantime any input about the blank thingy would be appreciated.

Anyway here's some pics.

It's called a Vapor Separator.

Took the vapor (gas) separator off the tank. Put gas in it and wiped in clean. Almost immediately I could see gas wicking out of the seam. See pic.


I have a replacement valve on order from Volunteer Vette since my carcoal canister appears to be connected

Gotta open the garage door now. Gettin' kind of fumey in here.

Anyone know if a canister can back-up the valve? How do you know if the canister is functioning properly?
