Review on 🔒 ACDelco GM GT231 Fuel Tank Filler Cap, Black - Original Equipment by David Perry

Not for 2004 Silverado with non-threaded fuel cap. If the one you're replacing has threads on the side of the cap, it's probably the right one. Mine has two points on the side that screw my cap into the fork. Check out the picture I posted and compare yours to this one before ordering. This cap screwed into the connector but the connector wire didn't fit in the hole on the fuel filler flap that the old one came out of so I returned it. I needed a GT289 cover. However, this is a high quality ACDelco part.
