I've posted this question on some LR-specific forums but might as well toss it out here as well.
While on my little adventure last week, I started noticing strong gas fumes from the truck. The first time this was with a full tank and after some big climbs/descents, so I figured I had simply sloshed some fuel up into the vapor recovery system. it was gone the next day.
The following day I started getting it again when traveling on some rough trails at low speeds. This time I again had a near full tank. Again, it eventually stopped but the smell was worse than the first time.
A couple days later and again I got the smell, stronger than ever. This time I had 1/4-1/2 tank of fuel and wasn't on particularly rough trails.
Then on the trip home I noticed it out side the vehicle after an interstate run, though not inside. Obviously this was a smooth, high-speed run.
I haven't dug into the truck yet to see if I can find anything obvious. My thoughts were that the evap system must have a problem, and that I'm only getting the smell when traveling slowly because the fumes are blowing away at higher speeds. However, I believe a failed line in the evap system should throw a code which I haven't seen happen.
I've found a number of references to gas tank problems on the earlier LR3s, but nothing for the later trucks (mine is an '07). Most of the chatter I've found on-line goes something like 'I had some gas smell in the truck and took it to the dealer, but I don't remember what they did'. So it looks like there may be a trend, but I haven't found any actual repairs.
Another data point: this was happening around 6000' and 90-100 degree temps.
I'm going to be under the truck this weekend doing some maintenance and will be doing a visual inspection of the fuel/evap piping while I'm there, but if any of you have any peals of wisdom you'd like to toss out I'd be happy to listen.
