Happened to my '01 back in June; it has about 150,000 miles on it. I ended up paying $75 for a tow roughly 8 miles to my house because I was concerned that I might run into trouble. In hindsight, I should have saved that money. I did the "lift the bed" method as opposed to dropping the tank, and it was rather easy. Not sure if it's the same with an '02, but I removed all the bolts (4 or 6...can't remember) and just loosened the 2 rearward most bolts. Lifted and supported the front of the bed, and that made the pump, harnesses, etc accessible. Made the job very easy...
