Question about warranties....2nd owner

I was wondering if 2nd owners have any kind of warranty? I own a 2000 Passport with around 58,000 miles, 2nd owner.

The reason I ask is that I think I have the bad fuel sending unit problem which seems to be common with these cars.

For the Isuzu it was a 10yr, 120k warranty for owner #1, for owner #2 it was 5yr 60k.

The Passport it was the standard Honda warranty of 3yr/36k for owner 1,2,3....

thanks!
