Question: Isn't this an obvious safety hazard/design flaw? Beyond that, is
Feature! Hot vaporized fuel is much more noticeable by smell, I'm surprised you let it get this far. :-)
there anything I should plan on replacing other than the large fuel lines leading from the tank? Is there a seal on the fuel tank sending unit thatcould also be leaking?
The sender seal is up on top. Big O-ring, and unlikely to be bad. There are several rubber lines at the tank, for feed, return, and vent. -- Jim
