Mention the word ‘filter’ and I guarantee that most people will think immediately of either the oil or air filter – very few, I am sure, will mention the fuel filter. Nevertheless, as important as both air and oil filters would seem... read more

Trying to pick up that last drop of fuel out of the tank is a challenge, especially if the car is developing high g-forces while cornering or under acceleration. However, ensuring complete evacuation of the fuel tank just as the race is finishing not... read more

Any engine man these days, no matter how young or old, will have at least a pretty good idea of how electronic fuel injection works. With its speed, temperature and pressure sensors, maps and ECUs, the digital nature of the technology is well underst... read more
