Easier to do with the tank of the bike and upside down but can be done with it on but takes a lot of patience of which I have none LOL
The one i am talking about is the same size as the 11105 (used for oil changes) but a lot thicker...is that the 11387A? i know there is one that is about 1" that seals the line assembly to the tank...that isn't what you're talking about tight?
