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 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 equipment
We have the latest and best equipment in order to properly clean, test, and calibrate injectors for Duramax, Cummins, and Power Stroke engines.
Hartridge IFT-70
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
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
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.
Hartridge HA230 with HJ04
Siemens 6.0L upgrade kit
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.)
