Not much other than fit could go wrong. I have to trust that the venting works, as I don't have any simple test. I only wish it had been all that I needed to fix the check-engine light diagnostic code. I'm still trying to isolate the culprit for that issue, but at least I have eliminated the possibility the gas cap was at fault. Review: Good cap. - This cap fits like factory. The only thing is it doesn't have the strap to attach it to the vehicle. It's not a deal breaker and I would buy another one of I have to. ## Features - Meets or exceeds OEM specifications - Caps fit both shallow and deep cam filler necks - vented, non-vented and vented anti-surge - Fenderwell Fuel Caps are zinc-plated and dichromate dipped for superior corrosion resistance - Some models are made from rugged plastic - EEC Fuel Caps meet OEM specifications and Federal and State Emission Requirements ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000C2UDXK | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #819,462 in Automotive ( See Top 100 in Automotive ) #2,539 in Automotive Replacement Fuel Tank Caps #26,260 in Automotive Replacement Fuel System Equipment | | Brand | Gates | | Color | Black | | Customer Reviews | 4.4 4.4 out of 5 stars (1,267) | | Date First Available | March 1, 2007 | | Exterior Finish | Machined | | Global Trade Identification Number | 00072053408003 | | Item Weight | 0.01 ounces | | Item dimensions L x W x H | 3.6 x 3 x 3.6 inches | | Item model number | 31830 | | Manufacturer | Gates | | Manufacturer Part Number | 31830 | | Material | Plastic | | Model | Fuel Tank Cap | | OEM Part Number | 31830 | | Product Dimensions | 3.6 x 3 x 3.6 inches | | Style | Modern | | UPC | 072053408003 | | Vehicle Service Type | Car, Truck | ## Product Details - **Brand:** Gates - **Color:** Black - **Exterior Finish:** Machined - **Item dimensions L x W x H:** 3.6 x 3 x 3.6 inches - **Material:** Plastic ## Images ![31830 OE Equivalent Fuel Tank Cap - Image 1](https://m.media-amazon.com/images/I/81nvGCukAfL.jpg) ## Questions & Answers **Q: Will this fit a 2001 Mazda B3000 truck?** A: I'm not sure but there is a option up top to see if it will fit your vehicle. **Q: Ford box truck motorhome** A: Does you gas cap require threads or not.

Not much other than fit could go wrong. I have to trust that the venting works, as I don't have any simple test. I only wish it had been all that I needed to fix the check-engine light diagnostic code. I'm still trying to isolate the culprit for that issue, but at least I have eliminated the possibility the gas cap was at fault. ### ⭐⭐⭐⭐⭐ Good cap. *by B***S on August 19, 2020* This cap fits like factory. The only thing is it doesn't have the strap to attach it to the vehicle. It's not a deal breaker and I would buy another one of I have to. ### ⭐⭐⭐⭐⭐ Works on 2001 Mazda B3000 *by A***R on October 14, 2024* Bought this to replace the inconvenient keylock style fuel cap that my 2001 Mazda B3000 came with. Screwed the replacement cap right in, good seal without any indicator lights coming on. Good value for the cost. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/8936829-31830-oe-equivalent-fuel-tank-cap](https://www.desertcart.ro/products/8936829-31830-oe-equivalent-fuel-tank-cap) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-11*
