Hi Paul
I recently went exploring in the carbon canister of my '70 Mk3 Spit. My
canister seemed to be plugged so I looked up the price for a new one in VB.
After I got over the shock of the price I decided to have a look. The canister
is really nothing more than a bunch of carbon pellets packed between two pieces
of screen and filter material (I think there was also a spring but I can't
remember). The top and bottom screens were packed solid with solidified muck
(technical term). I opened the canister and removed the top filter and screen
then I dumped the works in a bucket. I made new pieces of screen and washed
the filter pieces in simple green. I removed all of the lumps and stuff from
the carbon and then put everything back together. I know that the carbon may
be spent but the canister is working just fine. Before I cleaned it the garage
always smelled like gas but not since the cleaning.
Good luck
