About Us

InjectorsDirect.com was founded in San Luis Obispo, California  in 2009. After having to replace the injectors in an LB7 Duramax, we realized that there needed to be a better way for diesel pickup owners to get quality fuel injection parts for their trucks at reasonable prices. We now offer parts for Duramax, Cummins, and Power Stroke Diesel engines. Our expert technicians are trained to test and service all the products we offer.

Our Mission

At InjectorsDirect.com it is not only our job to provide customers with the best experience possible, it is our purpose. As the industry-leading team, we challenge the status quo. We never compromise in the pursuit of continuous improvement, striving to become the best versions of ourselves.

Reliability: We rely on our teammates to work together effectively to complete our daily tasks, and to achieve our strategic goals. We help each other succeed.

Dedication : We are dedicated to professionalism, speed, and efficiency, always exceeding expectations.

Our Facility/Equipment

InjectorsDirect.com has invested over $1,000,000 in the latest state of the art equipment in order to properly clean, test, and calibrate injectors for Duramax, Cummins, and Power Stroke engines.

Our current equipment includes:

Common Rail

These are used to test all Duramax injectors (2001-present), common rail Cummins injectors (2003-present), & Power Stroke injectors (2007-present).

Hartridge IFT-70

Hartridge IFT-70 (3)

Single line common rail injector test stands (A.K.A. pop testers).  These machines are capable of producing 700 bar (10,000 P.S.I.), and are used to test basic injector functions, roughly check delivery/return ratio (at lower pressures), visually inspect nozzle spray patterns, as well as flush out any residual diesel fuel and other contaminants that may be present in the injectors.

Hartridge IFT-200

Four line computerized common rail injector test stand/flushing rig.  The first of it’s kind in the US; This machine is capable of 2000 bar (29,000 P.S.I.), and is used to test basic injector functions, roughly check delivery/return ratio (at higher pressures), as well as flush out any residual diesel fuel and other contaminants that may be present in the injectors.

Hartridge CRI-PC 04B-CZ

Hartridge CRI-PC 04B-CZ (5)

Four line automated common rail injector test stand with pressurized backleak measurement.   This machine is capable of testing all common rail injectors (including the newest generation piezo injectors).  This machine is capable of 2000 bar (29,000 P.S.I.), and is used to duplicate the each injector’s performance as if it were installed in an engine.  It is computer controlled, and fully automated.  It is programmed to run very precise and specific tests on each particular injector.  These tests are conducted at numerous different pressures and operating conditions (pulse width & I.P.M.).  Each test step digitally measures & analyzes the injector’s response time, delivery volume, return volume, return pressure, and return temperature.  Each test also includes a solenoid coil resistance test to ensure the solenoid is in good condition, as well as a static back leak test to ensure that the injector’s internal seals are intact and performing as they should.  This machine tells us everything there is to know about each particular injector.

Maktest 1026

Maktest 1026

Single line common rail injector test stand with electronic measurement. Our first test stand; This machine is capable of 2000 bar (29,000 P.S.I.), and performs a similar operation to our CRI-PC, except it is only capable of testing one injector at a time.

 

H.E.U.I.

(Hydraulically actuated, Electronically controlled, Unit Injector.)

This equipment is used to test 7.3 & 6.0 Power Stroke injectors (1994-2007)

Hartridge HA230 with HJ042 Siemens 6.0L upgrade kit

Hartridge HA230 with HJ042 Siemens 6.0L upgrade kit (2)

This four line machine is capable of testing 4 H.E.U.I. injectors simultaneously.  It allows us to test basic injector functions, visually check each nozzle’s spray pattern as well as delivery volumes at numerous different pressures and operating conditions (pulse width & I.P.M.)

Beware of other companies who claim to “test” or “refurbish” injectors. There are many in the marketplace who only do basic function tests (pop testing), rather than comprehensive testing. A basic function test will give you very little information about the injector’s actual performance and condition! Don’t waste your hard earned money buying injectors that have not been properly tested & calibrated!
