Overview

The DVPARTS 17620-ZL8-003 gas cap is a direct replacement designed for a wide range of Honda lawn mower engines, including the GC135, GC160, GC190, GCV135, GCV160, GXV160, GCV190, and GX100 models. Priced at just $6.47 with a 4.4-star rating from 95 reviews, this cap solves the common headache of a lost, cracked, or leaky OEM cap without needing to visit a dealer. It’s built for homeowners and DIYers who need a quick, affordable fix to get their mower back in action.

Who Should Buy This

Homeowners with aging Honda mowers – If your original gas cap has gone missing, cracked from UV exposure, or won’t seal properly, this is a budget-friendly drop-in replacement. It fits a broad range of Honda small engines from the last two decades.
DIY mechanics who hate dealer trips – Instead of hunting down an OEM part at a premium price, this cap offers a solid aftermarket alternative for under $7. It’s a no-brainer for anyone comfortable with basic mower maintenance.
Owners of multiple Honda-powered equipment – If you have a GC190 on your mower, a GXV160 on a pressure washer, and a GX100 on a tiller, one cap fits them all. Keep a spare on hand for emergencies.
Budget-conscious buyers – At this price point, you can replace a faulty cap without second-guessing. It’s cheaper than a tank of gas and solves fuel evaporation, leaks, or starting issues caused by a bad cap.

Key Features Breakdown

Compatibility with 10+ Honda engine models – This cap works with GC, GCV, GXV, and GX series engines from 100cc to 190cc. That covers most Honda walk-behind mowers, generators, pumps, and small equipment. Check your engine model number (stamped on the valve cover) to confirm fit.
Direct OEM replacement design – The cap twists on and locks just like the original 17620-ZL8-003, 17620-ZL8-013, 17620-ZL8-023, and 951-10300 parts. No adapters, no modifications. It’s a true plug-and-play swap.
Vented cap for proper fuel flow – A small vent allows air into the tank as fuel is consumed, preventing vacuum lock that can starve the engine. This is critical for consistent starting and running performance.
Durable plastic construction – Made from UV-resistant plastic, it won’t warp or crack quickly under sun exposure. It’s not metal, but for the price, it’s tough enough for seasonal use.
Price under $7 – At $6.47, it’s one of the cheapest fixes you can make to a mower. A dealer OEM cap can run $12–$18, so this saves you real money.

Pros

Wide compatibility – Covers a huge range of Honda engines, making it a one-size-fits-most solution for small engine owners.
Budget-friendly – Under $7 is a steal for a part that solves fuel system issues like leaks, evaporation, and hard starting.
Easy installation – No tools needed. Just unscrew the old cap and screw on the new one in under 30 seconds.
Proper venting – Restores correct air pressure in the tank, which many cheap aftermarket caps fail to do. This prevents stalling and fuel starvation.
Solid 4.4-star rating – 95 reviews back it up. Most users report it fits and seals perfectly on their Honda mowers.
Lightweight and compact – Doesn’t add bulk to your mower. You can even toss a spare in your tool bag for emergencies.

Cons

Not a genuine Honda part – It’s an aftermarket replacement. While it works for most users, the plastic feel and fit might be slightly looser than OEM. A small number of reviewers mention a less snug seal.
Vent can clog over time – The tiny vent hole may get gummed up with old gas residue or debris. You’ll need to clean it periodically with a toothpick or compressed air to maintain proper venting.
No tether or strap – Unlike some OEM caps, this doesn’t have a retaining strap to keep it attached to the mower. It’s easy to misplace if you set it down while refueling.
Limited color options – It comes only in black. If you want a color-matched cap for a specific mower, you’re out of luck.

Bottom Line

If your Honda-powered mower is suffering from fuel leaks, hard starting, or a missing gas cap, the DVPARTS 17620-ZL8-003 replacement is a smart, low-cost fix. It fits a broad lineup of Honda small engines, installs in seconds, and restores proper venting for reliable performance. For $6.47, you’re getting solid value—especially compared to pricier OEM options. Just be aware it’s an aftermarket part with slightly less premium feel, and keep an eye on the vent for clogs. I recommend buying one as a spare even if your current cap works, because when a cap fails mid-season, you’ll be glad you have it.

Frequently Asked Questions

Q: Will this cap fit my Honda mower with a GC160 engine?
A: Yes, it’s specifically listed as compatible with the GC160, along with GC135, GC190, GCV135, GCV160, GXV160, GCV190, and GX100 models. Check the engine model number on the valve cover to be sure.

Q: Does this cap have a vent, or is it sealed?
A: It’s vented. The cap includes a small air vent that allows the fuel tank to breathe, preventing vacuum lock. If your mower runs for a few minutes and then stalls, a bad cap is often the cause, and this one fixes that.

Q: Is this cap made by Honda, or is it a generic part?
A: It’s an aftermarket replacement, not a genuine Honda OEM part. It’s designed to match the dimensions and function of the original, but the plastic and sealing feel may be slightly less refined. Most users find it works fine for normal lawn mowing use.

How It Compares

Here is a head-to-head comparison of the two products you listed.

Important Clarification: The two items you provided are not lawn mowers. Mower A is a replacement gas cap (a small engine part) for Honda engines. Mower B is a brand name (Briggs & Stratton) but lacks any model, specs, or features—it is likely a reference to the company itself or an incomplete listing. To provide a fair comparison, I will treat “Mower B” as a generic, unspecified Briggs & Stratton lawn mower (which could be a push, self-propelled, or riding model) and compare it to the Honda engine gas cap for context. If you intended to compare two actual mowers, please provide full model names. For now, this comparison is between a small replacement part (Honda cap) and a generic Briggs mower.

Quick Verdict

If you need a reliable, affordable gas cap for a Honda small engine, Mower A wins for its specific utility and low price; if you need a complete, widely-trusted lawn mower from a top brand, Mower B (Briggs & Stratton) is the obvious choice for actual mowing.

Side-by-Side Comparison

Feature	Mower A (Honda Gas Cap)	Mower B (Briggs & Stratton Mower)
Price	$6.47	$8.73 (likely a reference price, actual mowers cost $150–$3,000+)
Power Source	Gas engine component (cap)	Gas engine (Briggs & Stratton)
Cutting Width	N/A (not a mower)	Varies by model (typically 21–30 inches)
Self-Propelled	No	Yes (many models) / No (some push models)
Best Yard Size	N/A (repair part)	Small to large (depending on model)
Warranty	None specified (part only)	2–3 years (typical for Briggs mowers)

Where Honda Wins

Ultra-Low Price for a Specific Need – At $6.47, Mower A is a cheap, direct replacement for Honda engine gas caps (models GC135, GCV160, etc.). If your Honda mower’s cap is broken, this is a budget-friendly fix instead of buying a new mower.
High Compatibility – This cap fits over a dozen Honda engine types (GC, GCV, GXV, GX100 series). It’s a universal-fit part for many popular small engines, making it a handy spare for DIYers.
Solid User Rating – With a 4.4/5 rating from 95 reviews, users confirm it seals well and fits correctly. It’s a reliable, no-frills part that does its job.

Where Briggs Wins

Complete Mowing Solution – Mower B (Briggs & Stratton) is a full lawn mower, not a part. It includes an engine, deck, wheels, and controls—ready to cut grass immediately. You cannot mow with a gas cap.
Massive User Trust – With 22,608 reviews and a 4.8/5 rating, Briggs & Stratton is one of the most trusted engine brands globally. This reflects decades of reliability, parts availability, and service support.
Versatility for Different Yards – Briggs offers push, self-propelled, and riding mowers. You can choose cutting widths from 21 to 30+ inches, self-propelled drive for hills, and engines from 140cc to 500cc. This flexibility suits small city lawns to large estates.

Which Should You Buy?

Buy Mower A if…

You own a Honda lawn mower with a GC135, GCV160, GXV160, or similar engine and need a replacement gas cap. It’s a cheap, quick fix.
You’re a DIY mechanic who wants a spare cap for your Honda small engine (e.g., for a pressure washer or generator).
You have a broken gas cap and don’t want to buy a whole new mower. This part costs less than a fast-food meal.

Buy Mower B if…

You need a complete, reliable lawn mower for cutting grass. Briggs & Stratton offers proven engines, easy parts access, and a wide range of models.
You want a mower with strong user reviews and brand trust. The 4.8/5 rating from over 22,000 buyers is hard to beat.
You have a small to medium yard and want a self-propelled or push mower that will last years with basic maintenance.

Don’t buy either if…

You’re comparing two actual mowers. Please provide full model names (e.g., Honda HRX217 vs. Briggs & Stratton 500 series) for a true head-to-head. This comparison is between a gas cap and a brand name.

Head-to-Head Comparison: DVPARTS Gas Cap vs. Briggs & Stratton Oil Filter

Quick Verdict

This comparison is fundamentally flawed because these are not lawn mowers—they are replacement parts for different engines—so the “winner” depends entirely on which specific mower engine you own and what part you need to replace.

Side-by-Side Comparison

Feature	DVPARTS 17620-ZL8-003 Gas Cap	Briggs & Stratton 492932S Oil Filter
Price	$6.47	$9.30
Power Source	Replacement part for Honda GC/GCV/GXV/GX engines	Replacement part for Briggs & Stratton engines
Cutting Width	N/A (not a mower)	N/A (not a mower)
Self-Propelled	No	No
Best Yard Size	Any size (part fits many Honda mowers)	Any size (part fits many Briggs mowers)
Warranty	Not specified	Not specified

Where Honda Wins (DVPARTS Gas Cap)

Cost-Effective Fix: At $6.47, this gas cap is significantly cheaper than a dealer replacement, making it an affordable solution for a leaking or broken cap on popular Honda small engines (GC135 through GX190).
Broad Honda Compatibility: The DVPARTS cap fits 10 different Honda engine models, including the common GCV160 and GCV190 found on many walk-behind mowers, pressure washers, and generators. This versatility is valuable for owners of multiple Honda-powered equipment.
Simple Installation: Replacing a gas cap requires no tools—just twist off the old cap and twist on the new one. The 4.4-star rating from 95 reviews suggests it works reliably for most users, with the main complaint being fitment on some specific models.

Where Briggs Wins (Briggs & Stratton Oil Filter)

Overwhelmingly Proven Reliability: With 15,496 reviews and a 4.8-star rating, this oil filter has been tested across an enormous user base. The high rating indicates consistent quality, proper sealing, and effective filtration across countless engines.
Critical Engine Protection: An oil filter is far more essential for engine longevity than a gas cap. It traps metal particles, carbon, and debris to prevent engine wear. Skipping a proper oil filter replacement can lead to costly engine failure—a gas cap failure only causes fuel spillage or evaporation.
Genuine OEM Part: Briggs & Stratton’s own branded filter ensures exact fitment and performance specifications. DVPARTS is a third-party manufacturer, which can sometimes lead to tolerance issues. The OEM part gives peace of mind for critical engine maintenance.

Which Should You Buy?

Buy the DVPARTS Gas Cap if: You own a Honda-powered mower (e.g., HRX217, HRR216, or any model with a GC/GCV/GXV/GX engine) and your current gas cap is cracked, missing its tether, or leaking fuel. This is a cheap, easy fix that solves a common problem—just double-check your engine model number against the compatibility list.

Buy the Briggs & Stratton Oil Filter if: You own a Briggs & Stratton-powered mower (common on Craftsman, Troy-Bilt, Snapper, and many other brands) and it’s due for an oil change. The 492932S filter is a standard replacement for many Briggs single- and twin-cylinder engines. Follow your mower’s maintenance schedule—typically every 50 hours or annually.

Buy neither if: You are actually looking for a complete lawn mower. These are parts, not mowers. If you need a mower, consider models like the Honda HRX217 (self-propelled, great for ¼–½ acre) or a Toro Recycler with a Briggs engine (good value for smaller yards). Instead, use this comparison to determine which part you need for the mower you already own.
