Review on πŸ”’ ACDelco GM Original Equipment GT306 Fuel Tank Filler Cap - Enhanced Performance & Reliability by Justin Zilinskas

Revainrating 5 out of 5

Suitable for 2006 Hummer H2 SUT

Good OEM replacement. These caps usually cause the evap code to appear on OBDII readers. Replace the cap first if you don't notice anything abnormal. Fits 2006 Hummer H2 SUT (truck but I'm sure it will fit other models too).

Pros
  • Nice packaging
Cons
  • ---
