Just gotta go slow and steady, you don't wanna squeese the pump handle all the wayCan't find much fault but I do have an issue with the filler neck in the fuel tank. Maybe just UK spec? But the hole is the exact size for just the tip of an unleaded nozzle which means it's really hard to see when it's nearing full
Besides, the tank hold around 11 liters from empty to full, so it doesn't take long anyway.
And you have the two breather holes above anyway don't you? So you'll notise when it's full or not, shouldn't come surpricing on you each time you fill it up.
