KEMSO 340LPH High Performance Fuel Pump for Jeep Cherokee…

Now, if you’re not just looking for a stock replacement but genuinely want to upgrade your Jeep XJ’s performance, especially if you’ve got engine modifications or are planning forced induction, the KEMSO 340LPH fuel pump is definitely one to consider. This isn’t a complete module assembly; it’s the pump itself, designed to be installed inside your existing fuel pump module (or a new aftermarket one). What makes it high-performance? The 340 liters per hour (LPH) flow rate, which is significantly higher than stock and capable of supporting up to 600 BHP in various applications. This is fantastic news for modified 4.0L engines. The fact that it’s designed for gasoline or E85 also adds to its versatility.

A-Premium Mechanical Fuel Pump Compatible with Jeep & AMC…

Okay, now let’s address the elephant in the room regarding the A-Premium Mechanical Fuel Pump. It’s crucial for XJ owners to understand that this particular pump is NOT for late-model Jeep XJ Cherokees (1997-2001). Those models use an electric, in-tank fuel pump. This mechanical pump is designed for much older Jeep models and AMC vehicles that utilized a carbureted engine or early fuel injection systems that relied on a block-mounted, mechanical pump driven by the engine’s camshaft. You can see from its extensive fitment list that it covers a wide range of older AMC and Jeep vehicles from the 70s and 80s, including CJ5, CJ7, older Cherokees (pre-XJ generation), and even Wranglers up to 1990. While it’s a perfectly good replacement for those specific applications, it is not compatible with the electric fuel system of the 1997-2001 Jeep XJ. If you happen to have one of those classic Jeeps, then this is a direct, reliable replacement for your mechanical pump, designed to deliver consistent fuel pressure for carbureted engines.

• Vehicle Fitment-1: Compatible with AMC Ambassador, AMX, Concord, Eagle, Gremlin, Hornet, Javelin, Matador, Pacer, Rebel, Spirit (various L6 3.3L, 3.8L, 4.2L models from 1970-1988)
• Vehicle Fitment-2 & 3: Compatible with Jeep Cherokee 1984-1985 L4 2.5L, Cherokee 1974-1983 L6 4.2L, CJ5, CJ6, CJ7, Commando, DJ5, J10, J20, Scrambler, Wrangler 1987-1990 L6 4.2L
• Reference Number: MF0009, M6737, SP1006MP, 6737, 3197738, 3216577, 3223045, 3225283, 3228191, 5066236AA, 6440892, 6441177, 6441249, 6470572, 6470979, 6471197, J3228191, 5208020
• Specifications: Inlet Outside Diameter: 0.313 IN; Inlet Quantity: 1; Outlet Quantity: 1; Gasket Included: Yes; Maximum Pressure: 7 PSI; System Pressure: 5 PSI

Pros:
– Excellent direct replacement for older, carbureted Jeeps and AMC vehicles.
– Comes with a gasket for installation.
– Restores proper fuel delivery for mechanical pump applications.

Cons:
– NOT compatible with 1997-2001 Jeep XJ Cherokees.
– Only suitable for vehicles that originally came with a mechanical fuel pump.
– Low pressure (7 PSI max) is insufficient for modern EFI systems.

Best for: Owners of older Jeep models (pre-XJ, CJ series, early Wranglers, or pre-1997 Cherokees that used a mechanical pump) looking for a reliable, OEM-style replacement for their mechanical fuel pump. Not for 1997-2001 XJ.

User feedback summary: For those with the correct vehicle application, this pump is generally lauded as a good, affordable replacement that functions as expected. Users report easy installation and proper fuel pressure for their classic Jeeps and AMC vehicles.

Helpful Comparison Insights

When you’re sifting through options for the best fuel pumps for Jeep XJ performance and reliability, it really boils down to your specific needs and the year of your XJ.

The A-Premium Electric Fuel Pump Module Assembly (both the standalone and the “Set of 3” with straps) and the Carter Electric Fuel Pump Module Assembly are your go-to choices for direct, OEM-style replacements for 1997-2001 XJs. They are designed to drop right into your tank and restore your Jeep to its original factory fuel delivery.
* A-Premium offers a more budget-friendly option, with the “Set of 3” being particularly attractive if your fuel tank straps are also due for replacement. Their one-year warranty provides basic assurance.
* Carter generally sits at a slightly higher price point, but it justifies this with a reputation for OEM-level quality and enhanced features like the Clean Screen strainer and silver contacts, which suggest potentially better longevity and consistent performance. If you want a more robust OEM-style replacement and don’t mind spending a bit more for a known brand, Carter is a strong contender.

Now, if you’re chasing more power and your XJ is far from stock, the KEMSO 340LPH High Performance Fuel Pump is in a league of its own. This isn’t a drop-in module, but a high-flow pump that installs inside your existing module. It’s built for serious performance upgrades, capable of handling forced induction or heavily modified engines, and offers E85 compatibility and an impressive lifetime warranty. Don’t buy this if your XJ is stock; it’s overkill and might require other system modifications. But if you’re pushing boundaries, it’s the clear choice for maximizing Jeep XJ performance.

Finally, we have the A-Premium Mechanical Fuel Pump. It’s crucial to reiterate: this pump is NOT for 1997-2001 Jeep XJ Cherokees. Its low-pressure, mechanical design is exclusively for older, carbureted Jeeps or early EFI models that used a mechanical pump mounted to the engine block. If you have an older CJ, Commando, or a pre-1997 Cherokee with a mechanical pump, then it’s a perfectly viable and reliable replacement for that specific application. But for the target XJ years, it’s incompatible.

When deciding, consider: Do I need a direct OEM replacement for reliability? (A-Premium or Carter). Do I have significant engine modifications and need more fuel for performance? (KEMSO). And critically, what year is my XJ and what type of fuel pump did it come with? Always double-check fitment and pump type before buying.

Final Verdict

Choosing the right fuel pump for your Jeep XJ is a critical decision that impacts everything from daily drivability to off-road capability.

For the vast majority of 1997-2001 Jeep XJ owners looking to restore factory performance and enhance reliability without breaking the bank, the A-Premium Electric Fuel Pump Module Assembly is a solid, economical choice. If you’re concerned about older, corroded tank straps, the A-Premium Set of 3 adds excellent value by including those crucial components, making it a very convenient package deal. For those who prioritize a trusted brand name and want a replacement with enhanced durability features designed to potentially outlast the original, the Carter Electric Fuel Pump Module Assembly is a top-tier option, offering great peace of mind and often superior filtration.

However, if your Jeep XJ is heavily modified, running a turbo, supercharger, or a built engine, and you demand serious fuel flow to support high-performance applications, then the KEMSO 340LPH High Performance Fuel Pump is the undisputed champion. Its flow rate, E85 compatibility, and lifetime warranty make it the go-to for enthusiasts pushing their XJ’s limits. Just remember it’s a pump-only installation, not a full module.

And for the record, remember that the A-Premium Mechanical Fuel Pump is strictly for older, pre-XJ Jeeps and classic AMC vehicles; it’s not applicable for the 1997-2001 XJ Cherokees that use an in-tank electric pump.

Ultimately, by understanding your XJ’s needs – whether it’s a stock daily driver or a high-horsepower trail monster – you can confidently pick the best fuel pump to keep your legendary Cherokee running strong for years to come.

Comprehensive FAQ Section

Q1: What are the common symptoms of a failing fuel pump in a Jeep XJ?
A: Common symptoms include difficulty starting, a whining noise coming from the fuel tank, engine sputtering or stalling (especially at higher speeds or under load), a sudden loss of power, reduced fuel economy, and consistent misfires. If you notice a drop in your Jeep XJ’s performance and reliability, your fuel pump might be to blame.

Q2: Can I replace my Jeep XJ fuel pump myself, or should I take it to a mechanic?
A: Replacing an XJ fuel pump can be a DIY job for those with moderate mechanical experience and the right tools. It typically involves dropping the fuel tank, which can be challenging if the tank is full or if bolts are rusted. If you’re uncomfortable working with fuel systems, don’t have a safe way to support your Jeep, or lack experience, it’s best to consult a professional mechanic to ensure the job is done safely and correctly, preserving your Jeep XJ’s performance and reliability.

Q3: What’s the difference between a fuel pump module assembly and a pump-only replacement?
A: A fuel pump module assembly is a complete, pre-assembled unit that includes the fuel pump, the fuel sending unit (for your fuel gauge), a strainer, and often the housing. It’s designed for a direct drop-in replacement. A pump-only replacement, like the KEMSO, is just the electric motor and pump mechanism itself. This requires you to disassemble your existing module to replace just the pump, which can be more involved but might be preferred for performance upgrades or cost savings if other module components are still good.

Q4: Do I need a high-performance fuel pump for a stock Jeep XJ?
A: Generally, no. A stock Jeep XJ’s 4.0L engine operates perfectly well with an OEM-spec fuel pump, which provides sufficient fuel pressure and flow. A high-performance pump like the KEMSO is designed for heavily modified engines (e.g., forced induction, stroker builds) that demand significantly more fuel than stock. Installing one on a stock XJ usually won’t provide any noticeable performance benefit and might even cause issues if not properly regulated.

Q5: How long do fuel pumps typically last in a Jeep XJ?
A: The lifespan of a fuel pump can vary widely depending on driving conditions, fuel quality, and the quality of the pump itself. On average, a factory or good-quality aftermarket fuel pump for a Jeep XJ might last anywhere from 100,000 to 150,000 miles. Keeping your fuel tank at least a quarter full can help extend its life, as the fuel helps cool the pump. Regular maintenance and using quality fuel contribute to the reliability of your fuel pump.

Q6: Why is the A-Premium Mechanical Fuel Pump not suitable for 1997-2001 Jeep XJs?
A: The 1997-2001 Jeep XJ Cherokees use an electric fuel pump located inside the fuel tank, which delivers high pressure (around 49 PSI) for its electronic fuel injection system. The A-Premium Mechanical Fuel Pump is designed for much older, carbureted or early EFI Jeep and AMC vehicles (typically pre-1991) that use a low-pressure (around 5-7 PSI) mechanical pump mounted on the engine block. The two systems are fundamentally different and incompatible. Installing a mechanical pump on a late-model XJ would result in insufficient fuel pressure and the engine would not run.

Q7: What else should I consider when replacing my XJ’s fuel pump?
A: When replacing your fuel pump, it’s a good idea to also inspect or replace other related components. Check your fuel filter (it’s often recommended to replace it at the same time), fuel lines for cracks or leaks, and the condition of your fuel tank straps. If your new pump comes with a new sending unit, ensure the wiring harness connection is clean and secure. These small steps can significantly contribute to your Jeep XJ’s performance and reliability in the long run.
