Airtex Fuel Delivery Systems controls and improves its processes to prevent defects, providing exceptional quality products.  Throughout the design process, Airtex fuel pumps are put through rigorous testing to validate the design requirements. All fuel pumps are 100% tested during the manufacturing process as well.  Each unit must pass strict testing specifications before it is packaged and shipped.


AIRTEX Fuel Delivery Systems will be attending this year’s Automechanika in Frankfurt, Germany, September 16th through September 20th. As the U.S. preferred supplier of mechanical and electrical fuel pumps to the automotive aftermarket, OEMs and specialty manufacturers, Airtex is excited to be a part of this global event.


Airtex Fuel Delivery Systems, the world’s largest manufacturer of fuel pumps, has just launched the Spanish version of it’s award winning FuelPumpU.com technical training website. This online resource, which offers real-time educational assistance, as well as current and in-depth information and fuel pump replacement support will now be available both in English and Spanish. Technicians can now visit the website for a myriad of technical resources and videos on diagnostic training and fuel delivery education in the language of their choice.


When they are in the break room…on their drive to work…in the shower…maybe even on their bowling night, it is rumored that the engineers at Airtex spend their free time thinking of new ways to test our fuel pumps.



If you suspect the fuel pump has failed or after a fuel pump or fuel filter replacement and you experience low fuel pressure the cause could be a faulty fuel pressure regulator.


The oxygen sensor is located in the exhaust. Its job is to monitor the amount of unburned oxygen in the exhaust by sending electrical pulses to the Powertrain Control Module (PCM).

The oxygen sensor sends a fluctuating voltage signal depending upon the amount of oxygen in the exhaust stream. When the oxygen level is high (lean condition) the voltage signal is low and when the oxygen level is low (rich condition) the voltage signal is high. The voltage signal will vary from 0.0 to 1.0 volts. When the voltage crosses the .45 volt level it is considered a count. Having a high number of counts usually means the engine is running properly.


Opportunities in the field of diesel-truck and heavy-equipment repair have never been greater. Demand for diesel technicians is much larger than the supply. This is due to the fact that many of the older Master Technicians are retiring, and the availability of newly trained technicians is not keeping up with the increasing demand.

Seasoned technicians had the benefit of learning the newest technology as it was introduced, however, a new prospective diesel technician is faced with an overwhelming variety of newly developed technology.


If your car is not starting, it could be due to a number of reasons, one of which could be an ignition system problem. In order to diagnose problems in the ignition system, it’s important to break it down into the following parts: spark plug, coil, spark plug wires, distributor and ignition module and then check through each component.


Central port injection (CPI) was a new style of fuel injection first introduced in 1992. It was the primary fuel system in all the 4.3L V6 Vortec engines through 1995.

Individual fuel injectors are pricey, and the CPI concept was developed to reduce costs by using one fuel injector, which is centrally located within the manifold, to distribute fuel to each cylinder through nylon tubes with poppet valves.
