We will do everything we can to make sure that you get the service you need. We understand how important it is to receive your order as quickly as possible.
In most cases Drive On Diesel only needs one address, as long as your product is shipping to the same location as your billing information. In order to eliminate credit card fraud, your billing information must match the credit card you provide.

The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.

Drive On Diesel provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.

Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".

If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue. If a replacement is determined to be necessary, we will then arrange for your replacement part to ship out ASAP and issue any necessary return shipping labels and/or documents.

As is the case for the majority of the diesel products sold on Drive On Diesel, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Drive On Diesel will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.

What is a Core Charge?

A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.

30 Day Core Charge Hold

You authorize Drive On Diesel, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.

For diesel engines like the Cummins ISX (1998–2004), the fuel lift pump plays a vital role in ensuring consistent fuel pressure and flow to the high-pressure pump and injectors. Without proper lift pump function, your engine may struggle to start or run efficiently. The OEM 53262255RX Fuel Lift Pump is a direct replacement designed to meet Cummins specifications and help maintain reliable engine operation.

Why the OEM 53262255RX Fuel Lift Pump Matters:

  • Maintains Constant Fuel Pressure – Delivers steady fuel flow from the tank to the high-pressure fuel system, critical for reliable injection.

  • Supports Cold Starts – A strong lift pump helps maintain prime in cold conditions, reducing crank time and potential fuel system damage.

  • Reduces Engine Strain – Prevents the high-pressure pump from working harder than necessary, extending the life of fuel system components.

  • Ensures Smooth Engine Idle and Acceleration – Consistent fuel delivery helps avoid hesitation or stalling during start-up or throttle response.

  • Built for Durability – Constructed to match OE standards for long-term dependability in challenging operating environments.


When struggling with starting issues, erratic fuel delivery, or poor engine response, a faulty lift pump could be at fault. Upgrading to the OEM 53262255RX Fuel Lift Pump ensures proper fuel system pressurization and supports smooth, reliable engine performance. Trust TamerX Diesel Parts for high-quality OEM replacements designed to keep your Cummins ISX road-ready.

 
 

The fuel lift pump plays a crucial role in diesel engines by transferring fuel from the tank to the high-pressure injection pump. If it begins to fail, you may experience engine starting issues, stalling, or reduced fuel pressure. Diagnosing a failing lift pump early can help prevent damage to downstream components and avoid costly repairs.

Symptoms to Watch For

  • Hard Starting or No Start
    If your engine struggles to start or won’t start at all, a weak or dead lift pump may not be supplying enough fuel.

  • Low Power or Acceleration
    A failing pump might not maintain adequate fuel flow under load, resulting in sluggish performance or hesitation.

  • Air in Fuel Lines
    Bubbles in the fuel system often indicate a failing lift pump or a leak that’s allowing air into the system.

  • Unusual Noises
    A whining, clicking, or buzzing sound from the pump area can be a sign of mechanical wear or blockage.

How to Test a Fuel Lift Pump

  • Visual Inspection
    Check for fuel leaks, damaged fuel lines, or corroded electrical connections that could impact pump function.

  • Fuel Pressure Test
    Use a pressure gauge to measure the pressure at the inlet of the injection pump. Compare readings to manufacturer specs—low pressure indicates a weak pump.

  • Volume Test
    Disconnect the line at the injection pump and direct it into a container. Crank the engine and check for sufficient fuel flow. Weak or no flow suggests pump failure.

  • Listen for Pump Operation
    With the ignition in the "on" position (engine off), listen near the tank or pump location for a hum or vibration that indicates the pump is running.

  • Check for Trouble Codes
    Use a diagnostic scan tool to see if the ECM has logged any fuel delivery issues related to lift pump operation.

Final Thoughts

Testing a fuel lift pump doesn’t always require advanced tools. A basic fuel pressure gauge, a visual inspection, and a scan tool can reveal most problems. Addressing lift pump issues early helps maintain proper fuel delivery and protects the rest of your fuel system from strain or failure.

With regular upkeep, it can remain dependable for many thousands of engine hours before potential failure.
