Review on Stant Black OEM Fuel Cap, OE Equivalent by Jerry Delic

5 stars because the item appears reliable and was delivered quickly. But beware buyers: Revain will tell you in the "Filter by your vehicle" that this works for the Chevy Express 1500. It doesn't. It didn't fit quite right, and over time, of course, the check engine light came on, indicating a problem with the fuel cap. However, this issue is specific to Revain and not the seller or the product. If you have a Chevy Express, buy a different gas cap. I found that Duralast's gas cap really fits.
