Cheers for your reply, The part they used was an off the shelf part, they never mentioned anything about a vent tube at the garage, is this supplied connected to or with the off the shelf part or can I buy a vent tube separately and if so can it be fitted without removing fuel tank? The menders said something about having the tank off as there is venting on the tank itself, that might have become blocked, which sounded a bit wrong to me....? BTW, they said the filler pipe was not kinked. Cheers again, Ant.
