Fuel Tank Cap - Compatible with 2003 - 2004 Hummer H2 6.0L V8 GAS

In my online research of how to remedy "boiling gasoline" caused by vapor locks, I learned that a very common cause was simply a bad fuel tank cap. Parts Geek had a gas cap on stock for my 2001 Mitsubishi Montero, and at a great price. So I ordered one, it arrived within a few days as advertised, I installed it, and the problem seems to be fixed--saving me from expensive parts and labor costs at an automotive repair shop. The part did not come with a tether though, which is the only thing that could have been more convenient for my need. But I improvised by cannibalizing the existing fuel cap tether assembly. I removed it from its screw mount on the body, and then very carefully cut off the plastic protrusion that held the tether itself to the middle of the old gas cap (which allowed it to swivel). Replacing the tether over the reused plastic piece, I superglued it to the new gas cap, taking extra care to ensure the gas cap was free to swivel, and it works great!
