After letting my truck sit on an incline with less than a 1/4 tank of fuel a few weeks back, I couldn't get her to start. I managed to level the truck off and/ or get the fuel pump to kick on and the truck started back up and has started fine ever since. Since I live in the hilly area just outside of Wash DC, I don't want to leave the tank less than half full so yesterday, I topped her off and shortly afterward, I began to smell gas in the area of the left side rear passenger door. I didn't see anything yesterday when I topped her off but today there's enough gas on the bottom side of the tank to worry me. I didn't smell anything prior to topping off the tank but I know there's no "overflow" feature on cars and trucks that will let excess fuel drain out. As alluded to, when I first couldn't get the truck to start, I thought I may have a bad fuel pump. It's hard to see up on the side of the tank to see where a possible leak may be coming from but I'm going to try and jack her up in the apartment lot and take a look. Any ideas?
