Key Takeaways
- The Dorman 800-086 is a 3/8 inch steel-to-nylon fuel line quick connector sold as a two-pack.
- It uses nylon and alloy steel components with a quick disconnect and barb style design.

- You should inspect the connection carefully after installation because fuel leaks create a serious safety risk.
What Is the Dorman 800-086?
The Dorman 800-086 is a fuel line quick connector made for 3/8 inch steel tubing to 3/8 inch nylon tubing repairs. It comes from Dorman, a well-known aftermarket parts brand that makes replacement parts for common vehicle repair jobs.
This part sits in the small but important fuel repair category. Instead of replacing a complete fuel line assembly, you can replace the worn or damaged connector when the rest of the line still works correctly.
The key selling point is its focused 3/8 inch steel-to-nylon fit. That size detail matters because even a small mismatch can cause poor seating, loose connection, or a leak after the fuel system builds pressure.
Pick this if: You need a compact repair part for a damaged 3/8 inch steel-to-nylon fuel line connection.
Who It’s For
- DIYers who have already confirmed a 3/8 inch steel line and 3/8 inch nylon line connection.
- Technicians who want a two-pack fuel connector for small repair jobs and shop inventory.
- Vehicle owners who want to repair a damaged connector instead of replacing a full fuel line assembly.
Who Should Skip It
- You should skip it if your vehicle uses a different line diameter or a different connector angle.
- You should skip it if the steel line is rusted, crushed, cracked, or unsafe beyond the connector area.
- You should choose professional help if you cannot safely depressurize and inspect the fuel system.
Feature-by-Feature Review
Design and Build
The Dorman 800-086 uses a quick disconnect and barb style design for fuel line repair work. Its main job is simple: adapt 3/8 inch steel tubing to 3/8 inch nylon tubing.
The connector uses nylon and alloy steel components, which suit the part’s repair-focused purpose. The black finish also helps it blend with many fuel line areas under the vehicle or inside the engine bay.
This is not a full fuel line kit with long tubing sections, clamps, and extra adapters. You get two connectors, so the value depends on whether your repair needs this exact 3/8 inch configuration.
Fit and Compatibility
Fit is the most important detail with the Dorman 800-086. The part is listed as a universal fit connector, but universal does not mean every vehicle or every fuel line setup.
You need to confirm the outside diameter of the steel line, the nylon tube size, and the connector style before you install it. A 3/8 inch connector will not safely solve a 5/16 inch fuel line repair.
You should also inspect the line ends before fitting the connector. If the steel line has deep rust, burrs, crushed edges, or old seal damage, the connector may not seat as intended.
Ease of Installation
The Dorman 800-086 can install quickly when you have clear access to the fuel line. The small connector size helps in tight areas, but working space around the line still affects the job.
Before installation, you need to relieve fuel system pressure and clean the connection area. Dirt, old fuel residue, and damaged tubing edges can stop the quick connector from locking cleanly.
Trained technicians may finish this type of connector repair in a short service window. Most DIYers should plan extra time for access, cleaning, inspection, and a careful leak check.
Leak Resistance and Safety
A fuel line connector has one core job: hold the connection without leaking. The Dorman 800-086 supports that goal with a precise 3/8 inch steel-to-nylon design.
You should still treat the final inspection as part of the installation, not an optional step. After fitting the connector, check that the lock engages and inspect the area before normal driving.
Fuel leaks can create fire risk, odor, poor running, and failed safety checks. If the connector does not seat firmly, remove it and inspect the line instead of forcing the part into place.
Pack Size and Practical Value
The two-pack format gives you more flexibility than a single connector. You can use one connector for the repair and keep one as a spare, or handle two matching connection points.
This format also makes sense for small shops that see repeat fuel line repairs. A compact two-pack takes little storage space and covers a specific 3/8 inch steel-to-nylon repair need.
The value is strongest when the connector prevents a full fuel line replacement. It offers strong value for the price when the line itself remains usable and only the connector needs attention.
Pros and Cons
Pros
- 3/8 inch steel-to-nylon sizing matches a common fuel line repair need.
- Two-pack format gives you a spare connector or parts for two matching repairs.
- Quick disconnect and barb style design supports a clean connector replacement.
- Nylon and alloy steel construction suits underhood and fuel line repair use.
- It can reduce repair cost when only the connector needs replacement.
Cons
- Fit depends on exact 3/8 inch line size and connector style verification.
- It will not fix a fuel line that has major rust, cracks, or crushed tubing.
- You still need a careful post-installation leak check for safe use.
How the Dorman 800-086 Performs in Real Use
For a Damaged Connector Repair
The Dorman 800-086 makes the most sense when the connector failed but the nearby fuel line remains usable. In that case, the 3/8 inch steel-to-nylon adapter can save you from replacing more parts than needed.
For DIY Garage Work
For DIY use, the part works best when you already know the fuel line size and have enough room to work. The two-pack gives you a backup connector, which helps if you damage one during removal or installation.
For Shop and Technician Use
For shop use, the Dorman 800-086 is a simple inventory part for a specific 3/8 inch repair. Technicians still need to match the vehicle’s line diameter, connector style, and line condition before using it.
Is the Dorman 800-086 Worth the Price?
The Dorman 800-086 offers strong value for the price when it prevents a larger fuel line repair. You pay for a small connector instead of replacing a full line assembly that may still be in good shape.
It works best as a smart buy for everyday repair needs, not as a universal solution for every fuel leak. If your line size matches and the tubing condition is good, the two-pack format makes the purchase more useful.
You get the most value from this part when you verify fit before ordering. Guessing on fuel line parts can waste time and create safety problems, so measure first and install only when the match is clear.
How It Compares to Alternatives
The Dorman 800-086 is the better pick when you specifically need a 3/8 inch steel-to-3/8 inch nylon quick connector. If you need a 5/16 inch connection, Dorman 800-081 may fit that smaller size better.
If you need more parts for several fuel line jobs, a larger Dorman nylon fuel line repair kit can offer more flexibility. The Dorman 800-086 remains the cleaner choice when you only need this exact connector size in a two-pack.
Frequently Asked Questions
What does the Dorman 800-086 connect?
It connects 3/8 inch steel fuel line to 3/8 inch nylon tubing. That makes it useful for matching fuel line connector repairs where both sides use the correct size.
Is the Dorman 800-086 a universal fit part?
Yes, it is sold as a universal fit connector. You still need to confirm the fuel line diameter, connector style, and vehicle repair area before installation.
How long does installation take?
Installation time depends on access, line condition, and your repair experience. Trained technicians may finish quickly, while DIYers should allow extra time for cleaning, fitting, and leak inspection.
Is the Dorman 800-086 durable for daily use?
It uses nylon and alloy steel components for fuel line repair use. Long-term results depend on correct fit, clean installation, and the condition of the steel and nylon tubing.

You may need basic fuel line disconnect tools, hand tools, and safety equipment for depressurizing and inspecting the system. Tool needs can change based on your vehicle and access to the connector.
Can it fix any fuel leak?
No. It only helps when the problem is a compatible connector area. If the fuel line is cracked, badly rusted, crushed, or leaking from another location, you need a different repair.
The Bottom Line
The Dorman 800-086 earns an 8/10 because it solves a specific fuel line repair problem with a focused 3/8 inch steel-to-nylon design. It is a worthwhile investment when your connector is damaged, your line size matches, and the fuel line itself remains safe to reuse.
You should look elsewhere if your vehicle needs a different diameter, a different connector shape, or a larger fuel line repair. For the right 3/8 inch repair, this two-pack is a practical and cost-conscious choice.
