Biohazard

The exact nature of the fuel leakage was easy to see once I got the old tank grommet and the new one side-by-side.

First of all, the diameters are visibly off from each other...



I expected to see this but I also expected the old grommet would be hard and dried out but it was quite soft and pliable. Hmmmm.....



Yeah, not even kinda the same. Not sure where that old grommet came from but it looks nothing like the repro part. The old grommet slides up and down the fill tube with ease as it doesn't even come close to hugging the metal. You can easily see light between the tube and the o-ring whereas the new seal has to be pulled firmly into place on the fill tube. Pretty sure this is the weak link in the quest to keep my gasoline where it belongs.
