The only difference is that its rocker arm is powered electrically. An Injection Pump is the device that pumps diesel (as the fuel) into the cylinders of a diesel engine. The in-line fuel injection pump has the same number of fuel pressure mechanisms (elements) as engine cylinders. Problem #1 – Dirty Fuel. The Fuel Injection Pump is used in the individual pump system of a solid injection. Possibly the relay is bad. Once through the transfer pump, some of the fuel is bypassed to the transfer pump's suction side through the pressure regulator assembly. An engine's operating conditions keep changing rapidly, hence fuel injection system should be fast enough to adhere to the changes and vary the fuel supply quantity at that very moment. For the 911T, 1969 to 1971 models, Porsche used carburetors (Weber and Zenith-Solex). By pressurising and injecting the fuel, the system forces it into air that has been compressed to high pressure in the combustion chamber. China, is the leading manufacturer specializing in producing the Diesel Fuel Injection System Tester in China. The VTX fuel pump pushes fuel through the high pressure line and into the fuel rail at a little more than 50 PSI. REMOVAL & INSTALLATION.
