Hey all, been doing some searching and couldnt find anything, but literally out of nowhere after filling up sunday, my 08 yukon xl has a smell of gas around it. I had it in the garage last night and found that it is coming down from top of tank. right in middle where fuel pump goes. It is a slow leak but a leaak none the less. I was at 1/4 tank last night. so I am pretty sure it isnt coming from side of tank. when I wipe it away i can watch it slowly run down. As this is my only vehicle, i was wondering if anyone has had this and can give an idea. So when I drop the tank, i can have what I need to repair it. or what to look for
