i am having trouble refuelling my car, i have checked the purge value with obdII

Thanks for getting back to me.I would not drive along with my hose un-attached from canister to fuel tank! so you want me to disconnect purge line from valve under the bonnet is this correct. kind regards Graham

Was just suggesting you disconnect the canister when needing to fuel to verify the system was sealed without being able to vent, and a possible clogged canister. Didn't expect you to drive around with it unhooked.

I tried disconnecting the vent line from fuel tank, still the same! have got it down to stuck roll back valve/ or distorted. may be some ideas to budge it without removing tank. regards Graham
