WHY 12-VALVE FUEL SYSTEMS FAIL AND HOW BD SOLVES IT

The Bosch P7100 injection pump is the heart of the 94-98 12-valve Cummins, renowned for its mechanical simplicity and tuning potential. If your original pump is failing, our Stock Exchange P7100 pumps are remanufactured to OEM standards for a direct, reliable replacement. For those seeking more power, our High Power P7100 pumps are built and calibrated for specific horsepower targets and RPM ranges, providing the extra fuel needed for significant performance gains.

  • Hard Starting or No Start

    Often caused by a worn-out P7100 injection pump, failing overflow valve, or a weak lift pump unable to supply adequate fuel pressure.

    The BD Difference

    A remanufactured Stock Exchange P7100 pump restores factory fuel pressure and reliable starting.

  • Low Power and Poor Response

    Can indicate a failing injection pump, clogged fuel filter, or worn injectors.

    The BD Difference

    Can also be a sign of a mis-adjusted or stock fuel plate limiting fuel delivery.

  • Excessive Black Smoke

    Usually means too much fuel for the available air, from oversized injectors or an aggressive fuel plate setting.

    The BD Difference

    Could also point to an oversized injector set or a leak in the charge air system.

  • Engine Sticking at High RPM

    A classic sign that the stock governor springs are unable to control engine speed.

    The BD Difference

    An upgraded 3K or 4K governor spring kit lets the engine safely reach higher RPMs.

What is a fuel plate and what does it do?

The fuel plate in a P7100 pump controls the maximum travel of the fuel rack, which dictates how much fuel is injected. Changing the profile of the plate changes the fueling curve, allowing for more power.

Do I need a 3000 or 4000 RPM governor spring kit?

Choose a 3000 (3k) GSK for most street and towing applications to get a wider, more usable power band. The 4000 (4k) GSK is typically reserved for competition use where higher engine speeds are required.

My truck has an automatic transmission. Does that matter when choosing a pump?

Yes. P7100 pumps are calibrated differently for automatic and manual transmission trucks from certain year ranges. Always select the pump that matches your truck's specific transmission and model year.

What are delivery valves?

Delivery valves are located on top of the P7100 pump and control the timing and pressure of the fuel pulse sent to each injector. Upgrading them can result in a snappier throttle response and more aggressive fueling.

Are these parts emissions compliant?

Many performance fuel system components are not for sale or use on pollution-controlled vehicles. Please verify the emissions status on each product page for your specific state and federal regulations.

Do I need to upgrade my lift pump when I upgrade my P7100?

While the stock lift pump can support minor modifications, a high-volume lift pump is highly recommended for any High Power P7100 or significantly upgraded injectors to prevent fuel starvation and ensure consistent pressure.
