Why Top-Grade Delivery Valves Matter for Cummins Engines

A delivery valve plays a critical role in controlling fuel flow and pressure inside the VE-style injection pump on many Cummins applications. A worn or leaking valve can lead to:

• Poor acceleration and reduced power output

• Hard starting when the engine temperature fluctuates

• Increased fuel consumption and higher emissions

• Rough idling and uneven load response

Investing in a high-quality delivery valve translates into crisp throttle response and steady performance, day after day.

Revive Your Cummins Engine With New, Used, or Rebuilt Delivery Valves

Goldfarb & Associates offers a full range of new, rebuilt, and used delivery valves to keep your Cummins engine running strong.

New Bosch Delivery Valves

Our new units are ideal for overhaul projects and performance rebuilds where long service life is the top priority.

Rebuilt Delivery Valves

• We source our rebuilt units from over 500 remanufacturers across the globe 

• Externally cleaned and visually inspected by our certified technicians

• Get guaranteed OEM-grade quality and performance 

Choose rebuilt delivery valves as a cost-effective alternative to new valves, delivering reliable operation and extended service intervals.

Used Delivery Valves

• Carefully selected cores showing minimal wear on the valve head and spring seat

• Metal surfaces checked for corrosion, cracks, and thread integrity

• Offered “as-is” for budget-minded repairs or trial installations

Used valves are a practical choice for older engines or emergency swaps when parts are in urgent demand.

How to Choose the Right Valve for Your Cummins Setup

If you’re unsure which option your Cummins engine needs, here’s what you should do:

1. Identify Your Pump Model
   Confirm you have a VE-style injection pump on a 5.9 L Cummins platform.

2. Match Part Number
   Verify that your valve’s part number matches the Bosch standard for your pump application.

3. Select Condition Grade
   Decide whether you require the longevity of a new unit, the value of a rebuilt valve, or the cost-effectiveness of a used core.

4. Consider Usage
   High-duty commercial trucks and off-road machinery benefit most from new valves. Light-duty service rigs often perform well on rebuilt options.
