When was the last time you changed your fuel filter? Did it come with a square cut or triangular cut gasket for the lid? The NAPA filters come with a square cut and they will leak. The proper gasket is the triangular cut ones.

Get some brake clean and spray the entire area down really good so that it's clean and dry. Start the truck up and drive it for a bit if necessary and check for leaks. This way you can see where it the leak is comming from.

could be one of the sensors on the left hand side of your fuel bowl I have seen several of them leak. The fuel pumps are also pritty bad about leaking.

NAPA uses Wix filters so it's very possible you got the square cut seal. The fuel will leak down the bowl and fill the little recesses in the block and progressivly fill them toward the back until it leaks out the back of the block. If the fuel pump is going bad it's possible that it's leaking out the weep hole on the pump. Get it all cleaned up and it should be much more obvious where the leak is comming from.

The fuel lines are bad to dry rot in our modles, also look closely at the bottom, rear, passenger side of your fuel filter, they have been known to crack there! Also do you park your truck frontend pointed up hill, or downhill this might cause you to look in the wrong place. Check your lift pump, were the lines from the heads go in the back and see if the big bolt is leaking!

GOOD LUCK!

I also had a leak and my whole top of my motor was full of fuel.My lines where dry and cracked but that wasn't the problem.On the drivers side of the fuel filter there is fuel part that has two bolts that hold it on and inside there is a oring and thats what was leaking.It would also be a good idea to change your little hoses while you got it apart.
