1991 Dodge Stealth Fuel Pump: The Complete Guide to Replacement and Upgrade Options
If you own a 1991 Dodge Stealth, your fuel pump is one of the most critical components keeping your engine running. The factory fuel pump on the 1991 Dodge Stealth delivers adequate flow for stock driving, but after 30-plus years, it is likely tired, noisy, or on the verge of failure. Replacing your 1991 Dodge Stealth fuel pump with a reliable, high-performance unit is the single most important upgrade you can make to restore drivability, improve throttle response, and prevent being stranded. Whether you drive the naturally aspirated 3.0L V6 or the turbocharged version, the right fuel pump ensures consistent fuel pressure under all driving conditions.
Why Your 1991 Dodge Stealth Needs a New Fuel Pump
The original fuel pump on the 1991 Dodge Stealth was designed to meet the demands of a stock engine. Over time, internal wear reduces the pump's ability to maintain pressure. Common symptoms of a failing fuel pump include hard starting, hesitation during acceleration, surging at highway speeds, and a whining noise coming from the fuel tank area. If you notice any of these signs, it is time to replace the pump before it leaves you stranded.
Another reason to upgrade is if you have modified your engine. Adding a turbocharger, supercharger, or even a cold air intake and exhaust system increases the fuel demand. The stock pump simply cannot keep up with higher horsepower levels. A high-flow aftermarket pump ensures your engine gets the fuel it needs to run safely and make power.
Understanding Fuel Pump Flow Rates for the 1991 Dodge Stealth
Fuel pumps are measured in liters per hour (LPH) at a specific pressure. The most common upgrade for the 1991 Dodge Stealth is a 255LPH pump. This flow rate supports up to 500 horsepower at the flywheel, which is more than enough for most street and moderate track builds. For example, the Quantum 255LPH fuel pump is a proven performer, tested by RC Engineering to deliver consistent flow even at higher pressures, making it ideal for forced induction applications .
If you are building a high-horsepower turbocharged 1991 Dodge Stealth, you may need a pump with higher flow. The KEMSO 340LPH pump is an excellent choice for applications up to 700-800 horsepower . It is a direct replacement that fits the same space as the stock pump but delivers significantly more fuel.
Types of Fuel Pumps That Fit the 1991 Dodge Stealth
There are two main categories of fuel pumps for the 1991 Dodge Stealth: OEM replacement and high-performance upgrade.
OEM replacement pumps are designed to match the factory specifications. The Delphi FE0117 fuel pump is a direct OEM replacement for the 1991-1996 Dodge Stealth, available for both the DOHC and SOHC naturally aspirated engines . It is a reliable choice if you simply want to restore stock performance.
High-performance upgrade pumps offer higher flow rates and better durability. These include the Walbro GSS342 255LPH pump, which comes with an installation kit and supports up to 500 horsepower . The Holley 12-936 is another 255LPH in-tank pump specifically designed for the 1990-1997 Dodge Stealth and Mitsubishi 3000GT, rated for continuous duty and tested for up to 2,500 hours .
Key Features to Look for in a 1991 Dodge Stealth Fuel Pump
When shopping for a replacement fuel pump, pay attention to the following features:
1. Noise Level. Aftermarket fuel pumps can be loud. The Quantum 255LPH pump uses a clean sheet vane-impeller design that produces only a faint "wheen" sound during priming and is virtually silent when the engine is running . This is a major improvement over the vibrating hum of older Walbro pumps.
2. Bypass Valve Setting. For turbocharged and supercharged applications, a pump with a higher bypass valve setting is crucial. The Quantum pump's bypass valve is set at a higher PSI than the Walbro line, ensuring consistent fuel pressure under boost .
3. Check Valve Technology. A common issue with high-volume fuel pumps is hard starting after the car sits for a few days. This happens because the fuel drains back to the tank, losing pressure. The Quantum pump includes patented check valve technology to maintain static fuel pressure, but you can also add an inline check valve like the HFP-FT3 for extra assurance .
4. E85 Compatibility. If you plan to run E85 fuel, make sure the pump is compatible. The KEMSO 340 pump is designed for gasoline vehicles but is also E85 compatible .
Installation Tips for the 1991 Dodge Stealth Fuel Pump
Replacing the fuel pump on a 1991 Dodge Stealth is a job you can do in your driveway, but it requires patience. The pump is located inside the fuel tank, which means you need to drop the tank or access it through the rear deck.
Safety First: Always disconnect the battery negative terminal before working on the fuel system. Work in a well-ventilated area away from open flames. Relieve fuel system pressure by removing the fuel pump fuse and cranking the engine for a few seconds.
Tools You Will Need: A jack and jack stands, a fuel line disconnect tool, a screwdriver set, and a socket set. You will also need a new fuel pump strainer and a new fuel pump gasket or O-ring.
Step-by-Step Guide:
- Drain the fuel tank or use a siphon pump to remove as much fuel as possible.
- Disconnect the fuel lines and electrical connector at the top of the tank.
- Remove the fuel tank retaining straps and lower the tank carefully.
- Remove the fuel pump assembly lock ring using a hammer and drift or a special tool.
- Lift the pump assembly out of the tank. Take note of the orientation of the pump and the pickup sock.
- Remove the old pump from the assembly and install the new one. Many aftermarket pumps come with a complete installation kit that includes a new strainer, hose, clamps, and wiring connector .
- Reassemble in reverse order. Prime the system by turning the key to the ON position for a few seconds, then check for leaks before starting the engine.
Comparison of Top Fuel Pump Brands for the 1991 Dodge Stealth
The market offers several brands, each with its own strengths. Here is a quick comparison to help you decide.
Walbro is the most recognized name in aftermarket fuel pumps. The Walbro GSS342 255LPH pump is a proven performer, supporting up to 500 horsepower, and is available for the 1991 Dodge Stealth with a specific installation kit . However, some users report that Walbro pumps can be noisy and have had reliability issues over time.
Quantum Fuel Systems positions itself as a direct alternative to Walbro. Their 255LPH pump is quieter, has a higher bypass valve pressure, and comes with a lifetime warranty . The pump is QS9000 quality certified and includes a vehicle-specific installation kit. This is a solid choice if you want a quieter, more reliable pump.
Holley offers the 12-936 255LPH in-tank pump, which is a direct replacement for the 1990-1997 Dodge Stealth and Mitsubishi 3000GT. It is made in the USA and has been tested for continuous duty up to 2,500 hours . Holley is a trusted name in the performance industry.
KEMSO specializes in high-performance OEM replacement fuel pumps. Their 340LPH pump is designed to fit the same space as the Walbro GSS342 but offers higher flow, supporting up to 800 horsepower . KEMSO pumps come with a lifetime warranty, which is rare in the industry.
DENSO is an OEM supplier to many automakers. Their 950-0154 fuel pump and strainer kit is a direct OEM replacement for the 1991-1992 Dodge Stealth 3.0L turbocharged models . DENSO pumps are known for quiet operation and reliability, but they are priced higher than aftermarket alternatives.
How to Choose the Right Fuel Pump for Your 1991 Dodge Stealth
Your choice depends on your engine setup and driving goals.
For a stock 1991 Dodge Stealth 3.0L naturally aspirated engine, an OEM replacement like the Delphi FE0117 or the KEMSO 340 pump (which fits as a direct replacement) will restore factory performance . The 255LPH pump is overkill for a stock engine, but it will not hurt performance and gives you headroom for future upgrades.
For a 1991 Dodge Stealth 3.0L turbocharged engine, you need a high-flow pump. The 255LPH pumps from Walbro, Quantum, or Holley are ideal. They support the increased fuel demand of the turbo engine and provide consistent pressure under boost .
For a highly modified 1991 Dodge Stealth with a built engine or larger turbo, step up to a 340LPH pump. The KEMSO 340 pump delivers the flow needed for 700-800 horsepower applications .
Common Mistakes When Replacing a 1991 Dodge Stealth Fuel Pump
Avoid these pitfalls to save time and money.
Using a cheap, unbranded pump. Many low-cost pumps have no quality control program, no flow testing, and no warranty. They may fail within months. Stick with reputable brands.
Forgetting to replace the fuel strainer. The strainer is a vital part of the system. Reusing the old one can clog the new pump. Most aftermarket kits include a new strainer .
Not checking the wiring. The fuel pump connector on the 1991 Dodge Stealth is prone to corrosion. If the connector is damaged, replace it along with the pump.
Ignoring the check valve. If you install a high-flow pump without a check valve, you may experience hard starting. Consider adding an inline check valve to maintain fuel pressure when the car sits .
Why You Should Consider a High-Performance Replacement for Your 1991 Dodge Stealth
Even if you plan to keep your Stealth stock, installing a high-performance fuel pump is a smart upgrade. The new pump will deliver more consistent fuel pressure, which improves throttle response and idle quality. It also provides a safety margin in case the stock pump degrades further. With a lifetime warranty on some models, you never have to worry about the pump again.
