Review on ACDelco GT172 Original Equipment Fuel by Jorge Kehayas

This is a replacement for an expired gas cap on my '88 C4. I try to keep everything stock, or at least keep the right kind of era. While I had no luck with the oil cap, which now sports a cartoonish warning symbol, this cap is identical in material and texture. The last one lasted over 30 years, and while it doesn't look that fresh anymore, it eventually expired due to a rubber seal. If the new one lasts as long, it's very good.
