Modern trucks rely heavily on precise fuel delivery systems to maintain performance, fuel economy, and emissions control.

Port fuel injection has some big advantages, but automakers increasingly are using gasoline direct injection instead. The ...

In the past, race-type constant flow fuel injection (Fl) systems have met with little success on the street. Usually designed only for high-speed idle and wide-open throttle (WOT) operation, such ...

Electronic fuel injection is older than you think, the earliest example being the failed Bendix Electrojector system from 1957. Bosch bought the rights to the Eletrojector system and developed it into ...

Fuel injectors don't just deliver fuel. They meter it, shaping the spray so the air-fuel mixture burns in the way the engine wants it to. When deposits build up, injector fuel flow can decrease and ...

Mechanical injection systems rely entirely on engine driven components to meter, pressurize, and time fuel delivery. In these engines, a mechanical injection pump is driven by the engine's gear train ...

Having fuel injectors on all mass-produced vehicles is one of the biggest automotive breakthroughs of the past few decades. If you've ever gone through having to start an engine with a poorly tuned ...

One of the most ignored areas of building and maintaining a race car is the fuel system. The fuel tank, filters, vent system, and fuel line size all must be designed to work together to supply the ...

Replacing a fuel injector typically costs between $300 and $4,000, depending on your vehicle's make, engine size and fuel system complexity. This out-of-pocket estimate includes both parts and labor, ...
