I was trying to find a way to avoid buying the $19 moulded fuel line from my dealer and came up with this. I buy one of their pig tail fuel lines and a fuel line grommet from a 338xpt. Comes to $10. Then it is cheap to replace just the fuel line in the future. The last picture is of a 181, the tank had to be drilled with a 5/16 bit to open it up a little for the grommet. It seems like the 181 has a little smaller opening for the fuel line. This might work with the 266 series also.
