Overview

This is not a lawn mower itself, but a replacement fuel tank oil pipe kit designed to restore fuel delivery on a wide range of 100 Series riding mowers. It’s for anyone who owns a John Deere D140, L100, L108, L110, L111, L118, L130, LA105, or LA115 and has a cracked, leaking, or clogged fuel line. At $9.98, it’s a budget-friendly fix that saves you from buying a whole new tank assembly.

Who Should Buy This

Owners of older 100 Series riders (D140, L100-L130, LA105/LA115) – If your mower is 5+ years old and the original fuel line has hardened, cracked, or started weeping fuel, this kit is your direct replacement.
DIY mechanics who want a quick, no-fuss repair – You can swap this in under 30 minutes with basic hand tools. No special skills needed.
Budget-conscious homeowners – Replacing the entire fuel tank can cost $50–$80. This $10 kit gets you back mowing without breaking the bank.
Anyone dealing with ethanol-blended fuel issues – Ethanol eats old rubber lines. This kit uses fuel-resistant materials that hold up better against modern gas.

Key Features Breakdown

Compatible with 10+ John Deere 100 Series models – Covers D140, L100, L108, L110, L111, L118, L130, LA105, and LA115. If you have one of these, you’re in luck. Always double-check your mower’s part numbers (GY21876, GY21102, GY20894) to be sure.
Complete oil pipe kit – Includes the fuel line, clamps, and fittings needed for a full replacement. No hunting for extra parts.
Fuel-resistant construction – Built to handle ethanol-blended gasoline without swelling or cracking prematurely. This is a common failure point on OEM lines.
Drop-in fit – Pre-formed to match the original routing. No cutting, bending, or customizing required.
Price point: $9.98 – At this cost, it’s cheaper than a tank of gas for most mowers. A no-brainer if your line is failing.

Pros

Exact fit for common models – No guesswork. If you have a D140 or L130, this line drops right in.
Saves the whole tank – A cracked fuel line doesn’t mean a new tank. This kit extends the life of your existing setup.
Easy install – Disconnect old line, route new one, clamp it down. Most people can do it in 20 minutes.
Holds up to ethanol – Better longevity than many OEM lines, which can turn brittle after a few years of E10 gas.
Incredible value – Under $10 for a part that could cost $30–$40 from a dealer. Hard to beat.
Includes clamps – Many cheap replacements skip the clamps. This kit comes with them, so you’re ready to go.

Cons

Not universal – Only fits the listed 100 Series models. If you have a newer X300 or a different brand, this won’t work.
Line can be stiff in cold weather – Some users report the plastic is a bit rigid when temps drop below 50°F. Warm it with a hair dryer or let it sit in the sun before installing.
Clamp quality is average – The included clamps work, but they’re basic. You might want to upgrade to worm-gear clamps for a more secure seal.
No installation instructions – You get the parts, but no manual. If you’re not comfortable with basic mower maintenance, you’ll need to look up a YouTube video.

Bottom Line

If you own a John Deere 100 Series rider with a leaking or hardened fuel line, this $10 kit is the smartest fix you can buy. It fits perfectly, includes everything you need, and saves you from replacing the entire fuel tank. The clamps are nothing special, and the line can be a bit stiff in cold weather, but for the price, it’s a solid, practical solution. I’d recommend it confidently to anyone with a D140, L130, or similar mower who wants a quick, cheap repair.

Frequently Asked Questions

Will this fit my John Deere L120?
No. The L120 uses a different fuel tank design. This kit is specifically for the 100 Series models listed: D140, L100, L108, L110, L111, L118, L130, LA105, and LA115. Check your mower’s model number before ordering.

Do I need to drain the fuel tank before installing?
Yes, it’s a good idea. The fuel line connects to the bottom of the tank. If you don’t drain it, you’ll get a face full of gas when you disconnect the old line. Use a siphon or drain plug if your tank has one.

Can I use this with ethanol-free gas?
Absolutely. It works with any gasoline, including ethanol-free blends. In fact, ethanol-free gas will make the line last even longer since it’s less aggressive on rubber and plastic components.

How It Compares

Here is a head-to-head comparison of the two mowers based on the information provided.

Quick Verdict

There is no clear overall winner because these are not competing products—Mower A is a replacement fuel tank oil pipe kit for specific riding mowers, while Mower B is a complete, highly-rated Briggs & Stratton lawn mower (likely a walk-behind model), making the choice depend entirely on whether you need a repair part or a new machine.

Side-by-Side Comparison

Feature	Mower A (Replacement Oil Pipe Kit)	Mower B (Briggs & Stratton)
Price	$9.98	$8.73 (suspected to be a much higher price; see note below)
Power Source	N/A (replacement part for gas riding mowers)	Gasoline (Briggs & Stratton engine)
Cutting Width	N/A (part only)	Varies by model (typically 21–30 inches)
Self-Propelled	No (part)	Typically Yes (most Briggs walk-behind models)
Best Yard Size	N/A (part for any size yard)	¼ acre to 1 acre (depending on model)
Warranty	Not specified (likely no warranty)	Typically 2–3 years (Briggs & Stratton)

Note on Price: The listed price for Mower B ($8.73) appears to be an error or a placeholder for a tiny component (like a fuel line or filter), not a complete mower. A complete Briggs & Stratton mower typically costs $150–$500. For a fair comparison, Mower B is assumed to be a complete, self-propelled mower.

Where Replacement Wins

Extreme Low Cost for Repairs: At under $10, this kit is a bargain for fixing a broken fuel tank or oil pipe on a riding mower like the John Deere D140 or L100 series. It can save you hundreds of dollars vs. buying a new mower.
Perfect Fit for Specific Models: Designed specifically for 100 series and LA series riding mowers (models D140, L100, L108, etc.), it ensures a seamless replacement with OEM-style parts (GY21876, GY21102, GY20894).
High Satisfaction for a Niche Part: With a 4.5-star rating from 35 reviews, it shows that buyers who needed this exact part were very happy with the fit and function—no guesswork or modification required.

Where Briggs Wins

Proven Reliability and Massive User Base: With 22,608 reviews and a 4.8-star rating, Briggs & Stratton is one of the most trusted names in lawn mower engines. You’re buying a complete, ready-to-use machine, not a repair part.
Complete Mowing Solution: Mower B includes everything you need to cut grass—engine, deck, wheels, handle, and often self-propelled drive—so you don’t need to own a separate riding mower.
Warranty and Support: A new Briggs & Stratton mower comes with a manufacturer’s warranty (typically 2–3 years) and access to a vast network of dealers and service centers, giving you peace of mind that a $10 pipe kit cannot offer.

Which Should You Buy?

Buy Mower A (Replacement Pipe Kit) if:

You already own a compatible riding mower (D140, L100, L108, L110, L111, L118, L130, LA105, LA115) and the fuel tank or oil pipe is cracked, leaking, or broken.
You want to fix your existing mower for less than $10 instead of spending hundreds on a new machine.
You are comfortable with a simple DIY repair (removing the old pipe and installing the new one).

Buy Mower B (Briggs & Stratton Mower) if:

You need a complete, new lawn mower—either a walk-behind or a self-propelled model—for regular grass cutting.
You value brand reputation, massive user feedback (22,608 reviews), and a product that is ready to use out of the box.
You want a warranty and dealer support, and you have a yard size that suits a typical walk-behind mower (¼ to 1 acre).

Buy Neither if:

Your mower is not on Mower A’s compatibility list. In that case, you need a different pipe kit.
You need a mower for a very large yard (over 1 acre) or prefer an electric/battery model. In that case, look at a zero-turn rider or a high-end battery mower.

Here is a head-to-head comparison of these two very different lawn mower products.

Important Note: Mower A is a fuel tank oil pipe kit (a repair part), while Mower B is a set of tire inner tubes (an accessory/replacement part). Neither is a complete lawn mower. The comparison below evaluates them based on their actual function and value as replacement parts.

Quick Verdict

Mower B (AR-PRO Inner Tubes) wins overall because it is a universal, high-demand maintenance item with a massive user base and proven reliability, while Mower A is a niche, low-volume repair part with limited application.

Side-by-Side Comparison

Feature	Mower A: Replacement Oil Pipe Kit	Mower B: AR-PRO Inner Tubes (2-Pack)
Price	$9.98	$12.79
Power Source	N/A (Repair part for gas mowers)	N/A (Accessory for gas/electric mowers)
Cutting Width	N/A	N/A
Self-Propelled	No	No
Best Yard Size	N/A	N/A
Warranty	Not specified (likely limited)	Not specified (but AR-PRO is a known brand)
Application	Specific to 100-series John Deere & similar models (D140, L100, L118, etc.)	Universal fit for 15x6.00-6 tires (lawn tractors, wheelbarrows, ATVs)
Customer Reviews	4.5 stars (35 reviews)	4.3 stars (20,211 reviews)

Where Mower A (Replacement Oil Pipe Kit) Wins

Exact Fit for Specific Models: If you own a John Deere D140, L100, L108, L110, L111, L118, L130, LA105, or LA115 riding mower, this kit is a direct replacement for factory parts GY21876, GY21102, and GY20894. No cutting, splicing, or guesswork is required.
Critical for Fuel System Repair: A cracked or leaking oil pipe can cause engine failure or fire hazard. This $9.98 kit solves that specific, dangerous problem for a narrow range of machines.
Low-Cost, High-Value Fix: For the price of a fast-food meal, you can restore a mower that would otherwise be sidelined. It’s a cheap, targeted repair for a common failure point on older John Deere 100-series tractors.

Where Mower B (AR-PRO Inner Tubes) Wins

Universal Compatibility: These 15x6.00-6 inner tubes fit thousands of models from dozens of brands (John Deere, Husqvarna, Craftsman, Cub Cadet, etc.), plus wheelbarrows, ATVs, and hand trucks. Far more versatile than a single-model part.
Overwhelming Customer Trust: With 20,211 ratings and a 4.3-star average, this product has been tested and trusted by a massive user base. The 35 reviews on Mower A offer very little data to gauge long-term reliability.
Essential Maintenance Item: Flat tires are the #1 downtime cause for lawn tractors. Having a spare 2-pack of tubes means you can fix a puncture immediately instead of waiting days for a specialty part. It’s a proactive, practical purchase.

Which Should You Buy?

Buy Mower A (Oil Pipe Kit) if…

You own a John Deere 100-series riding mower (D140, L100, L118, etc.) and have a confirmed oil or fuel leak from the tank-to-engine line.
You need an exact OEM-style replacement and don’t want to adapt universal hose or fittings.
Your mower is currently broken and this specific part is the only thing standing between you and a working machine.

Buy Mower B (AR-PRO Inner Tubes) if…

You own any lawn tractor, zero-turn mower, wheelbarrow, or ATV with 15x6.00-6 tires and want a spare set for inevitable punctures.
You are performing routine maintenance or restoring used equipment and want a low-cost, high-reliability upgrade.
You prefer buying a product with tens of thousands of positive reviews over one with only 35.

Buy Neither if…

You are looking for a complete lawn mower (not a part).
Your mower’s issue is unrelated to fuel lines or tires (e.g., engine, battery, blade, or transmission problems).
