Fuel leak only when parked on a hill?
I have a fuel leak that happens as soon as I park my truck on my driveway facing downhill (not even close to steep, it has a slight slope). The leak is on the driver side about halfway down the block. It looks like its leaking from the fitting that you need a special tool to undo. There are 2 lines that both have this fitting and 1 line is thicker than the other. Both lines are coming from the top of the manifold 1 at the back (the thicker line) and 1 line coming off the top of the fuel filter housing area.
I started the truck and it continued to leak. I drove the truck around my block and then parked it in my garage so I could fix the leak. It wasn't leaking any longer. The truck was in my garage for 24hrs and it never leaked. I had to replace tensioner, idler pulley's and the serpentine belt. After I finished, I parked the truck back in the driveway on the hill and it started leaking again.
I use this truck to plow snow and for pulling my race car, so I don't drive it everyday. Im sure this has something to do with my problem.
Any help is appreciated!
Thanks in advance!!
