Fitting out cars

Although I love cars and driving, I'm not too much into all the technicalities behind them, such as when it comes to a transfer tank or other stuff stuff. My friend Ken in college was a complete car buff and would try to teach me as much as he could about cars, engines, fixing them up, jazzing them up and so on. I managed to grasp all the basics of car maintainance, which I must say came to my rescue several times, the fine details escaped me.
