A failing fuel tank filler neck must be fixed right away because it can cause fuel odors, seepage near the fill area, and evaporative emission control system (EVAP)-related check engine lights that can derail inspections. Rust, cracked welds, and damaged vent connections don’t just make fueling messy. They can also create vapor leaks that trigger repeat visits to the pump. If you notice stains around the filler inlet or smell gas after fill-ups, it might be time to get a replacement fuel tank filler neck.
This replacement needs to match your vehicle’s routing, mounting points, and hose and vent layout. These details matter because a slightly wrong bend or bracket can stress the joints, create new leaks, or make the fuel nozzle click off early. A good brand puts fit first, then backs it with corrosion resistance so that the repair lasts.
Aftermarket replacement fuel tank filler necks are as durable as their OE counterparts but they’re more affordable, which means you can get the same quality while saving money. Check out high-quality replacement fuel tank filler necks at CarParts.com today.

Our Score: 8/10
Omix
Omix, often sold as Omix-ADA, specializes in Jeep replacement parts. This brand focuses on OE-style replacements built for specific Jeep platforms, which helps when fitment gets picky. For filler necks, this specialization can matter because hose sizing and routing often vary across Jeep model years.

- Typical price point: $80
- Jeep-focused application coverage based on listing filters
- Sold individually for buyers who only need the neck
- Product descriptions position it as an OE-style direct replacement for specific years/models

Our Score: 8/10
Our Recommendation
If you want a strong balance of pricing, selection, and fitment cues, start with JC Whitney. It covers a wide range of applications, and it includes both individual necks and kit options. The product listings also tend to include the details that help you pick the right part without overthinking it.
Looking for a Replacement Fuel Tank Filler Neck?
Here’s what to consider:
Application and Fitment
Start by matching the vehicle details that drive fitment: year, make, model, engine, and any notes tied to body style or wheelbase. Then look at the part’s routing and mounting points. If your vehicle uses EVAP-related connections or sensor provisions, match that setup so you don’t end up with new warning lights after the repair.
Materials and Rust Resistance
Most filler neck failures are due to corrosion or fatigued joints near high-stress points. Look for materials and finishes that hold up to road spray and salt. If your old neck rusted near the cap area or mounting flange, treat corrosion resistance as a deciding factor rather than a nice-to-have.
Neck-Only vs. Kit
A new neck won’t fix cracked hoses or corroded clamps. If the rubber looks dry, swollen, or soft near the ends, replace these pieces at the same time. A kit can also cut down on repeat work because it refreshes the whole connection instead of only the metal section.
Buyers’ Reviews After Installation
Reviews won’t replace fitment checks, but they can reveal patterns. Look for comments about bracket alignment, sealing, and whether fueling feels normal again. If many buyers mention early nozzle shutoff or awkward fit, treat this as a warning sign and consider a different part or brand.
Total Cost
A filler neck can be bulky, and shipping can swing the final cost. Promotions and shipping programs can also change which brand makes the most sense. Factor in any extra hardware you’ll need, and consider the time cost of a return if the routing doesn’t match your vehicle.
