My evap leak...Joe (On Point) hooked up smoke machine & we found the culprit!! It was part of the fitting to the gas tank. Bad news, if piece on tank is broke you will have to replace your tank $$$$$ because that piece is part of the tank. Good news, fitting (not on tank) broke while being taken apart but enough was left for Joe to do his thing. Drilling, bushing, glue & we had a new part!!! Re-smoked & no leaks. Just have to go thu the drive cycle now. Joe came up with this fix & I am his 3rd repair for this & so grateful. Dealership would have replaced the tank, about $800. Part of contributing factor was my lift, installer "should" have made a longer (tie wrap) holder for harness to the tank, which on full articulation was really stretching harness to it's limits. That to was also addressed. Have described this procedure in layman's terms, but believe me this is a permanent fix & again, thanks Joe.
