I went to get diesel for the first time yesterday (V-Power Diesel), and I constantly got the 'click, click, click'
I was at the pump for ages trying to get the damn thing to work properly!!
It worked ok when I pulled the pump out slightly but then I was worried it would over fill and spill out?
So ended up not getting a full tank.
I dont remember this happening when I put fuel in the Dooper I borrowed though (I used BP that time)
Does turning it slightly to the left or right work?
