Is Your D150's Carburetor Failing?
The original carburetors on 1977-1988 Dodge D150s are now decades old. Time, wear, and modern ethanol-blended fuels can cause them to fail. You might notice your truck just doesn't run like it used to. Common signs of a failing carburetor include poor idling, reduced power, and even black smoke from the exhaust.
A Note on the Chrysler "Lean Burn" System
Many D150s from this era came with a computer-controlled "Lean Burn" feedback carburetor system. This system was designed for emissions control but is now a well-known source of running problems, including terrible idle, hesitation, and stalling. Many owners find that the best solution is to remove the entire Lean Burn system and replace it with a standard electronic ignition 🎬 See the easiest way to delete the Lean Burn system. and a new, non-feedback aftermarket carburetor.
Choosing the Right Aftermarket Carburetor
Since new OEM carburetors are no longer available, the aftermarket is your best choice. Your decision depends on your goals: are you looking for a simple stock replacement or a performance upgrade?
Performance Upgrade Brands: Edelbrock and Holley
If you want improved performance, reliability, and easier tuning—or if you're bypassing an old Lean Burn system—Edelbrock and Holley are the top choices.
- Edelbrock: Known for being easy to install and tune right out of the box. Their carburetors are popular for their simple two-piece design that helps prevent fuel leaks. Models like the Performer and AVS2 series are excellent choices for daily driven D150s, offering improved throttle response and performance.
- Holley: A legendary name in performance with a huge range of options, from mild street carburetors to full-race models. A Holley 2-barrel or 4-barrel carb can be a great upgrade for a stock or mildly modified 318 or 360 V8 engine, providing reliable performance.
Stock-Style Replacement: Uremco
If you prefer to keep your truck as original as possible and don't want to perform an upgrade, Uremco is a primary option. Uremco specializes in remanufacturing carburetors to meet or exceed original factory specifications. This makes them a direct, bolt-on replacement for your stock unit, designed to work with your existing setup. While they are remanufactured, Uremco has a long history in the industry.

Frequently Asked Questions
Can I replace the carburetor myself?
Yes, this is a very DIY-friendly job for someone with basic tools and mechanical knowledge. The process involves removing the air cleaner, disconnecting the fuel line, vacuum hoses, and throttle linkage, removing the four mounting nuts, and swapping the carburetor. 🎬 Watch this step-by-step D150 carburetor installation on a 318 engine. Always use a new gasket and be careful not to break the metal fuel line when disconnecting it. The entire job can usually be done in one to two hours.
What's the difference between a 2-barrel and 4-barrel carburetor?
The "barrels" are the openings through which air and fuel flow into the engine. A 2-barrel carburetor is standard on most stock D150 engines like the Slant-6 and 318 V8. A 4-barrel carburetor, like many offered by Edelbrock and Holley, has two smaller primary barrels for normal driving and two larger secondary barrels that open up under heavy acceleration for more power. Upgrading to a 4-barrel requires a compatible intake manifold.
Do I need to get rid of my Lean Burn system to install a new carb?
If you are installing a performance carburetor like an Edelbrock or Holley, you will almost certainly need to bypass the Lean Burn system. These carburetors are not designed to work with the original computer controls. The conversion typically involves installing a new, non-computer-controlled distributor and ignition module. If you use a direct remanufactured replacement from a brand like Uremco, it may be designed to work with the stock system.
Will a new carburetor need to be tuned?
Most aftermarket carburetors from brands like Edelbrock are designed to run well right out of the box with a baseline tune. However, for optimal performance and fuel economy, some fine-tuning of the idle speed and air/fuel mixture screws is usually required once the carburetor is installed and the engine is warm.
