Zippo lighter torch insert

I have two Zippo Blu lighters and they both do not work. One has a fuel leak. The other I tried to use after fueling and letting it sit for about 3 hours. The thing actually went poof--like a small explosion. Been using a Cigar Savor dual flamer, a ronson--they are sooo inexpensive, a Bic, and matches. While on vacation in Cancun at the cigar lounge they would light your smokie treat using a cedar strip.
