Subject: Extreme Tank Vacuum Solved

I was getting really annoyed with the tank suction problem, so I dug =
around in the archives and found a few hints as to what causes it.

A quick change of the EVAP canister, and the associated valve, and all =
is well.  Thanks to the archives, I nipped this before it creased the =
tank and caused a lead (expensive).

Ryan et al,

Often the symptoms of tank vacuum can be solved by removing the existing
canister and giving it a #$%&ing hard shake to loosen up the carbon
again.
The valve can be cleaned out with compressed air and the various lines
can be treated similarly or simply use a thin wire to ensure there are
no blockages.

Replacing the canister & valve obviously will ensure you don't have
problems in a long time, I just hope it wasn't too costly an
exercise....although clearly still less costly & problematic than having
to replace the tank.
