Alignment is the position of your wheels in relation to your vehicle and how they interact with the road. When your vehicle is properly aligned, your wheels will point in the same direction as the vehicle. To maintain proper control of your car, you must keep your wheels in proper alignment. Otherwise, steering will become difficult, your tires will wear unevenly and your fuel economy will decrease. 

If there’s an issue with your diesel fuel system, the most important thing to remember is to fix it sooner rather than later. With gas engines, you can often power through a fuel issue for quite some time - they’re irritating, but not often permanently damaging.
