robfg67 Posted March 7 Share Posted March 7 Any ideas on what to check for? As stated, it only smells when tank is filled. There are no leaks/drips. No smell at all when tank is below full. Link to comment Share on other sites More sharing options...
eaglescout526 Posted March 7 Share Posted March 7 Does the area around the sending unit look wet? My XJ kinda does the same. Link to comment Share on other sites More sharing options...
llhat Posted March 8 Share Posted March 8 could be as eaglescout suggest, takes only a gallon or few to get below sender access hole... recently went through this a few months ago on a NEW sender the O ring had deteriorated within months of new install... changed o-ring vendor and 'so far' OK other area are the two vapor line access on TOP of the tank... there's a valve up there connected to two vacuum lines leading to charcoal canister under hood. the lines could be rotten or have dislodged. the valves are retained with a rubber grommet also... you say no drips, that is also good... and bad for diagnosis check fuel fill also on fender side of tank.
