I don't know why it happens so freuquentlly...but when someone posts a problem I get the same problem here...way too coincidental!!! This problem needs a bunch of complaints to the bureau...http://www-odi.nhtsa.dot.gov/ivoq/ is the site. These POS disconnects throw gasoline when they're broken and are dangerous beyone belief. I just replaced mine today which were spewing gasoline three feet out from the connector. PLEASE PLEASE PLEASE file a complaint at the above website. This is one more thing about the LT that is just unacceptable.and beyond what is reasonable and is totally irreresponsible from a manufacturer.
