Is there a puddle of gas on the ground? See what is above the puddle for the leak location.


My 2002 model (same exact truck but a year newer) was setting a P0440-large leak code. A common problem with these trucks, as was with mine, is a rust through around the filler neck (fuel tank portion). I had 2 spots each about pea sized.
