Vershin Fuel Tank Gas Cap for Nissan & Infiniti — Replacement for 17251-1VZ0D, ABS with Rubber Seal

Vershin gas cap is a direct-replacement fuel tank cap engineered to fit many Nissan and Infiniti models, restoring a tight seal and helping prevent fuel vapor leaks and check-engine light triggers.

This replacement fuel cap is made to match original-equipment dimensions and mounting points so it integrates snugly with compatible Nissan and Infiniti vehicles. Constructed from ABS plastic and quality rubber, the cap includes two locking-buckle options, a tether rope interface, and an OE-style design that replaces several part numbers (for example 17251-1VZ0D). The description below explains common fit questions, installation details, and how to confirm compatibility before ordering.

Which models and part numbers does this cap replace?

This Vershin cap is manufactured to match original data and replaces multiple OEM references. It is compatible with a wide list of Nissan and Infiniti vehicles, but you should verify the part number on your original cap first.

• Replaces OEM numbers such as 17251-1VZ0D, 17251-3JA0A, 17251-9BD0E, 17251-4BA03, 17251-9EG1C.
• Common Nissan fits: Altima (2013–2018), Sentra (2013–2019), Frontier (2011–2020), Murano (2015–2020), Pathfinder (2013–2020), Versa series.
• Common Infiniti fits: FX35, QX60, Q50, Q60 and several older G/M/EX models — check the vehicle list and your cap’s part number to confirm.

How do I install the Vershin fuel tank cap?

Installation is straightforward and requires no tools. Turn the cap until you hear a click; the cap packs two buckle options to match tether configurations on different vehicles.

• Align cap with filler neck, then twist clockwise until you hear at least one audible click.
• Choose the suitable locking buckle and attach it to the cap tether interface to secure the rope.
• If your vehicle uses an existing tether, route and fasten the cap’s rope at the factory anchor point.

What materials and performance features does the cap offer?

The Vershin cap uses durable ABS and protective rubber for longevity and chemical resistance. It’s engineered for strong airtight sealing to reduce fuel odor and minimize evaporative emissions that can trigger the check-engine light.

• ABS plastic body resists impact and weathering for long service life.
• High-quality rubber gasket ensures a secure, leak-resistant seal.
• Two-locking-buckle design adapts to various tether arrangements.

When should I replace my fuel tank cap?

Replace the cap if it no longer seals, is cracked, or if you detect fuel odors or an illuminated engine warning light. A failing cap may allow fuel vapors to escape or air to enter the tank, impacting vehicle diagnostics and safety.

• Signs: check-engine light (CEL) related to evaporative system, fuel smell, visible cracks, or loose fit.
• Action: inspect the cap gasket and threads; replace immediately if damaged.
• After replacement: ensure clicks when tightened and that tether is secured to avoid loss.

Who is this for? This Vershin gas cap is designed for Nissan and Infiniti owners who need an accurate, OE-like replacement for a worn or damaged fuel tank cap. It's ideal for DIY vehicle maintainers, fleet managers replacing multiple units, or anyone troubleshooting evaporative system warnings. Before purchasing, confirm the OEM reference on your current cap matches one of the replaced part numbers or verify fit with your vehicle year and model to ensure a proper match.
