Update, called into a local Mower Store, and was told that the size wasn't normal, and they didn�t have a correct size Tube to fit the Chainsaw Oil Bottle. Thinking a little outside of the square, we went to a local Motor Bike Sales and Repair Shop. The gentleman in the workshop, was amazing. He looked at the Oil Bottle, took it away, and returned with a piece of blue tube, he then pulled the old tube out of the Filter, replaced it with the blue tube and he then continued fitting the Filter inside the Oil Bottle, and pulling the tubing out of the little hole. I just couldn't believe it, and he said to me, I've got everything at home to fix my Grass Trimmer. He was so nice. Arranging payment for his service and the tubing, he shook his head and said: �there�s no charge, I don�t want anything�. Isn�t that amazing service. I�ve attached a photo, in the Gallery showing the installed Tube within the Oil Bottle, alone with another photo which relates to where the Oil Tube enters and exits under a white plastic disc, Tube entry and exit is shown in Yellow. I don�t know how to remove that white plastic disc as it�s very firmly fitted. I would again appreciate your support and assistance in working this out. Many thanks Kindest regards, Sherrie.
