Carter Fuel Systems Expands Fuel Pump Line Coverage
Carter Fuel Systems, a U.S.-based manufacturer of complete fuel system solutions, has introduced 47 new part numbers covering a series of model year applications ranging through 2014. Extending coverage to more than 21 million additional passenger vehicles, the new part numbers include (40) fuel pump module assemblies, (1) hanger assembly, (3) direct-injection mechanical fuel pumps,
Royal Purple’s Max-Atomizer: Spring Cleaning For Fuel Injectors And Fuel System Components
Inside and out, even cars can need a little spring cleaning from time to time. As miles build up, today’s direct injected engines are especially susceptible to suffer from clogged and otherwise fouled injectors, robbing engines of power, decreasing fuel economy and negatively affecting emissions and engine responsiveness. To address all of these issues and
Modern Fuel Control Diagnostics: Sorting Through the Datastream
When confronted with a fuel control problem on a modern vehicle, I’ll normally use short- and long-term fuel trims to determine if the problem is caused by one of many failures such as a vacuum leak or a leaking fuel pressure regulator. If you’re like me, you’ll occasionally access the air/fuel ratio (AFR) sensor serial
Hyundai Fuel System, Emissions Diagnostics
Hyundai has done a good job of improving its offerings over the years from both an aesthetic and mechanical viewpoint. Complemented by a strong warranty and good value, the carmaker has been able to increase its market share year over year. If you aren’t seeing these cars in your bay, it’s only a matter of

Why Direct Injection Engines Develop Carbon Deposits
Direct injection in its current form has been around since 1997. During the next 10 years, Volkswagen, BMW, Mercedes Benz and many others introduced engines with direct injection. Today, almost all new engines have direct injection. When the early direct-injection engines hit the three-year or 30,000-mile mark, some developed driveablity problems due to carbon build-up
BMW Fuel System Repair Essentials
The BMW N54 fuel pump recall a few years ago brought to light the importance of the integrity of the fuel system and how it can contribute to the overall reliability of a vehicle. These fuel quality issues apply to all BMW vehicles with either port or direct injection. The underlying message here is that if the cleanliness and overall integrity of the fuel tank is ignored, it will damage any fuel pump. This is why addressing the fuel tank is essential during any pump replacement to prevent costly comebacks that can also hurt your reputation.
10 Signs A Fuel Injector Needs To Be Replaced
In the past 30 years, the fuel injector has moved from the intake manifold to the combustion chamber. During this evolution, injectors have become more precise in dispensing fuel. If this precision is thrown off by restrictions, electrical problems or fuel problems, it can cause driveability issues. These are the top 10 signs fuel injectors need service or replacement.
How Does The EGR And Secondary Air Injection Work With The Catalytic Converter?
The perfect internal combustion vehicle would be able to put the exact amount of fuel and air into the combustion chamber. If the perfect combustion event happened, you would get nothing more than water and carbon dioxide. There would not be any unburned fuel or oxygen. What would be needed to make this happen? Direct injection into the combustion chamber is a good start. You would also need the perfect combustion chamber free from hot spots – areas of unwanted turbulence or carbon build up. In the mean time, we have exhaust gas recirculation systems (EGR), secondary air injection and catalytic converters to reduce emissions
Diagnosing Inoperative Fuel Pumps
As I’ve discovered recently, times change and so do the procedures for diagnosing inoperative fuel pumps. Just a few weeks ago, I diagnosed a case in which the owner had started his vehicle for several months by spraying starting fluid (ether) into his truck’s air intake before he cranked the engine.
