Hi has anyone come across problems when putting Diesel in,It sometimes takes forever to put £10 in the diesel keeps rushing up to the top and spilling out and I have to wait a minute for it to go down before I can carry on ?

 

Just had this problem again putting £20 in the Diesel froths up and just rushes to the top and spills out it took me over 10 minutes to get 20 quid in it.
This problem has only just started since it was filled up with £50 which went in no problem.
