Review on Dorman 55300 HELP Fuel Tether by Mike Lunde

This is normal but when used with a Gates 31832 gas cap on a 2001 GMC Sierra the ring will not work. It is recommended to drill a hole in the top of the black cover and use a push pin to secure the cable. To avoid damaging the ventilation system, remove the black cap from the white valve gasket before drilling. The black cap can be removed by pulling it to the side while rotating the white valve assembly down and around the black cap until the locking tabs release.
