Hi all , since last set up have had a new and improved version more secure and safe , Reece Talbot is the man responsible for 3D printing an insert ,which fits into the inside of petrol cap which the extra 8mm fuel pipe goes through a filed out 7mm hole on cap to the inside, then pushed through the insert and the insert is then pushed into the inside of of the cap . Make sense lol ??
pics to follow with pipe attached
