On gas engines, the fuel delivery system is pretty simple - an electric pump draws gas from the tank, and pushes it to the injectors. Diesel systems are a little more complex. At Wensel Service Centers in Spring City, Allentown, & Reading, PA, we like to keep you informed about what’s on your truck, how it works, and how to maintain it, so you stay reliably on the road.

Whether you drive a Powerstroke, Cummins, or Duramax, your fuel system will work in essentially the same way. Although there are minor differences between them, they all have the same main components.

The fuel system on a diesel engine is more complicated than simply delivering fuel from the tank to the cylinders. Mechanical parts, electronic components, filters, separators, injectors, and more must all work together to keep your engine running. Due to the extremely high pressures diesel engines operate under, and the inherent nature of diesel fuel, there are a lot of factors that go into an effective diesel fuel system - how well it’s sealed and even the temperature outside can make a difference.

By knowing what your truck is equipped with, how it works, what it’s for, how to diagnose an issue, and keep it all maintained, your Ford, Ram, or Chevy truck will be on the road for many miles to come.
