AC Delco Gas Cap: GT231

This gas cap is just what you need to get your vehicle in good working order again.

Specifications:

  • Brand New AC Delco Gas Cap
  • Direct replacement
  • Built to strict quality control standards
  • Threaded Non-Locking design

Your fuel system uses both vacuum and pressure to ensure that as few gasoline vapors reach the air as possible. The gas cap regulates this balance. The cap has relief and pressure valves that regulate the pressure in the tank. Over time the gas cap can cease to work properly due to dirt, wear, and damage. In modern cars this will cause your check engine light to come on (usually after you fill up). If you notice your check engine light comes on after a fill up first check the cap for tightness. Then give the light a few days to go off. If your gas cap is the culprit then this replacement is what you need. Most cars the light will go out after 10-12 cycles of the key as long as nothing else is affecting the fuel vapor system.

Good as original
Tried several aftermarket caps that gave me Check Engine Lights. Also, the part that attaches the cap to the Tahoe interfered with tightening the cap and getting it loose. This cap works correctly and has resulted in no check engine lights. The one to buy. Caps with a rubber o ring gasket at the top of the threaded part are not good.,
