Obviously, your fuel delivery system is an extremely important aspect of the running condition of your truck. At Harold's Used Auto Parts Inc in Philadelphia, our expert team of mechanics can treat and clean your fuel delivery system, ensuring you get the most out of your fleet.  Keeping the fuel system clean is essential, particularly with high mileage diesel engines. Sediments and carbon buildup can dramatically affect pumps, filters, lines, and injectors. There are many important reasons to have your fuel system regularly checked and cleaned.

First, it’s a part of preventative maintenance. When the system is clean, everything from the tank to the cylinder experiences less wear and therefore needs less repair. If the pump is working overtime to deliver fuel, or gummed up and dirty injectors are fighting themselves to operate, those parts are wearing out far more quickly than necessary.

Secondly, dirty fuel components affect efficiency very negatively. Fuel consumption skyrockets and engine output decreases when injectors don’t function properly. Power is wasted and drained by parts that aren’t lubricating correctly, and unnecessary stress on components robs your engine of productivity. Carbon buildup from ineffectively burned fuel ruins valve trains, piston efficiency, and catalytic converters. It’s an altogether poor experience.

Whether you’re experiencing fuel system issues, or simply want to ensure that you don’t, our technicians have you covered. For all your commercial truck maintenance and repair needs, and for the best diesel and fleet service shop in Philadelphia, call or stop by Harold's Used Auto Parts Inc today.
