Do diesel engines have fuel pumps?
While a diesel pump is responsible for pumping out diesel fuel, a fuel pump can also be responsible for pumping out gasoline, depending on the type of engine. Both gasoline and diesel engines are internal combustion engines, which means they both have a mixture of air and fuel that is ignited to power the vehicle.
